Tune types
How We Work Together
Mods, speed-density, boost, or 24X/Torqhead? Prefer Email or Cable Loan — a single Postal tune isn’t meant for long-term use on those setups. Boosted and 24X/Torqhead require Email or Cable.
Basic Tune
Chip $115 · OBD1 $100 · OBD2 $100 · LS1 $100 shipped (US return postage included)
Quick non-power fixes: rear gear and/or tire size (’94–’97), VATS / AIR / EGR / skip-shift removal, speed-density conversion, or a stock-feeling swap PCM. Postal only.
Need spark, fuel, or automatic transmission changes — or you have real mods? That’s a Power Tune.
Power Tune
Postal: chip $215 · ’94–’95 $200 · ’96–’97 $200 · LSx $225
Everything in Basic, plus torque/HP work, optional MPG lean strategies, and auto shift firmness / points / TCC. Stock LT1s often land in the ~20–30 rwhp range from timing and fine-tuning alone.
- Stock or bolt-on cars wanting better throttle response, power, and mileage
- Injectors, cam, heads, displacement, or compression changes
- Iron ↔ aluminum head swaps; PCM-controlled auto shift behavior
Postal Power is not available for 1985–1995 TBI/TPI, trucks, 24X/Torqhead, or boost — use Email or Cable Loan instead.
MPG Improvement (option)
Open-loop AFR is leaned from your base; closed-loop targets a lower O2 voltage so the PCM runs leaner when sensors are active. Customers have reported large real-world gains (e.g. stock ’94 L99 Caprice 30+ MPG highway moderate setting; stock ’97 LT1 ~14–15 → ~19 MPG with aggressive driving).
Postal mail
Basic & Power · free US return ship
- For 1994+ flash-based PCMs (F/Y-body LT1 and later OBD2), you remove your PCM from your vehicle and mail it to me. I tune it to your specs, and mail it back to you (usually a week from you sending it until you receive it back).
- For 1993 and earlier chip-based PCMs — and the 1994–1995 trucks I tune — I send you a new tuned chip to install in your PCM. You do not need to send me your PCM for those years. Optional piggyback adapter from TunerCat (G1 for LT1/TPI, G2 for older TBI); some TBI need a soldered socket.
- I use USPS Ground Advantage or UPS Ground, which usually takes 1–3 business days to most of the USA. International welcome, often about a week.
Not ideal for cammed / injector / SD long-term use. Not available for boost or 24X/Torqhead.
Email method
Power only · OBD1 $200 · OBD2 LT1 $200 · LSx $250
You have Windows 10+ (7 may still work) and your own kit (ALDL cable, software, chip burner if needed). I email a base tune for your setup; no PCM downtime.
Free retunes
Up to three log-based retunes at my discretion/schedule (no time limit). Same setup only — small fine-tuning changes we have already discussed, not new mods or an entirely new setup (that needs a new order). Extra packs of three: $75 each.
Kit pointers
- OBD1: LT1 Pro Tuning kits from TunerCat (TunerCat + DataCat + ALDL cable; OBD1 Pro kit if you need chip burner/socket/blank chip).
- OBD2 LT1: LT-Flash kit (~$250) — flash + data-logger software included (TunerPro + custom XDF for DIY edits too), but only for ’96–’97 LT1 PCMs for now; or Jet Dynamic Spectrum Tuner (DST) (Summit Racing often has the best price, ~$500 now) and ECMPro Scan + enhanced GM diagnostics (~$199), which works with OBD2 LT1 PCMs.
- OBD2 LS1/24X/Vortec/V6: OBDX Pro VX + PCMHammer + PCM Logger (same zip as PCMHammer), or the Jet DST/ECMPro combo mentioned above.
- ’94–’95 LT1 flash only (no full kit): buy just an ALDL cable and use free load/log software — see Tips · EEHack / Flashhack.
Vehicle must be healthy: good ignition parts and knock/O2/MAF sensors & data, no intake/vacuum or exhaust leaks, or logs won’t support fine-tuning and performance will suffer.
Cable loan
Power · rent my kit · refundable core
- 1994–2005 flash-based PCMs: I send you an ALDL cable and software so you can load my tunes and data-log while driving. For 1994–1995 you will choose 12-pin or 16-pin on the order form (look under the dash) so I send the correct cable.
- Chip-based ECMs (1993 and earlier, and the 1994–1995 trucks I tune): I send you a chip burner/eraser, a blank chip, and an ALDL cable. You do not need to send me your PCM. Adapter recommended.
- Window: 7 business days (Mon-Fri, no legal holidays) of fine-tuning from first tune (weekends don’t count). Extra week: $75 (’94–’95), $75 (’96–’97), $75 (LSx).
- Core refunded when the kit returns; OBD2 kits deduct $25 for use/fees. Keep it a week past paid rental (or keep it) → core becomes a purchase.
Need: Windows laptop with USB, comfort installing drivers/software, factory ALDL port, internet for file exchange. Flashing risk is on you if power drops mid-write — keep batteries healthy / AC plugged in.
Same healthy-sensor requirement as Email.

Must-knows before you order
Please read this whole page before you order. The order form will ask you to confirm that you have.
What I can tune, and what you need
- I can tune only GM PCMs, not Ford, Chrysler, Dodge, or any foreign vehicles. Other GM PCMs beyond what's listed here? Contact me with a description of your setup and I’ll let you know whether I can help.
- Email and Cable Loan assume that your vehicle is in good running order including ignition and fuel components — with valid knock / O2 / MAF data, and no intake or exhaust leaks. I am not a mechanic. I am happy to offer suggestions from the 1000+ PCMs I have tuned, but I cannot guarantee I can figure out what is mechanically wrong with the car.
- Email: you already have a Windows laptop and your own kit. Cable Loan: if you can install a normal program, plug in a USB device, and email attachments, you should be fine. If you are a complete computer novice, this will not be for you.
- Postal: 1994+ flash PCMs you mail me the PCM. Chip years I mail you a new tuned chip — you do not need to send me your PCM.
Risks, retunes, and refunds
- Tuning not done in person will never be the same as in-person tuning, whether done in the car or on a dyno. That is why I offer free retunes — to get it “right” for the setup you ordered, not for new mods later. But email tuning is very convenient and gives us more time!
- Cable Loan on flash PCMs: if anything interrupts the programming/flashing process, it can damage the PCM. You will need to accept that risk and keep the laptop and vehicle batteries fully charged or plugged in to AC. The benefits far outweigh that small risk, but it is still there.
- The tune price is for the programming work. I do not refund it if you change your mind, the car has a mechanical problem, or it does not match a shop dyno.
- Cable Loan core is refundable when I get the kit back on time (OBD2 kits deduct $25 for use/fees). Keep it a week past the rental you paid for (or keep it) and I treat the core as a purchase.
How to reach me
- This is a side project (I am primarily a minister), so communication is email / web only — no business phone line.
- Use the contact form, email, or a message on the Facebook page.
Turn-around / weekends
- I do not work on the weekends, so I do not count Saturday/Sunday against a Cable Loan rental, and don't see/reply to emails then.
- Once I have payment and your PCM (or emailed file) — chip orders just need payment — I can begin work. Typical turn-around is about 3-7 business days (no weekends), depending on my current back-log.
- Free retunes are at my discretion and according to my schedule — sometimes a few days, other times a week or two or more. It may not always be a one-day turn-around.
Payment methods
Preferred: pay with Solana Pay (USDC). Settles on-chain with a public receipt — no card processor in the middle — $1 less than PayPal or cash, cashier’s check, or money order. Phantom, Solflare, Coinbase, and other Solana wallets work. I cover the SOL network fee.
I’ll take $50 off the first 3 orders paid with Solana Pay (USDC) (0 of 3 have paid).
Example: a Coinbase account can buy USDC with no purchase fee (still currently fee-free). Send it from the Coinbase wallet on Solana.
PayPal is still available for every order (card OK without a PayPal account). Cash, cashier’s check, or money order for Postal and Email only (not Cable Loan). No personal checks.
Shipping methods
- Postal (US): I ship the tuned PCM or a new chip back to you for free (USPS Ground Advantage or UPS Ground, usually 1–3 business days). You pay to mail a flash PCM to me. Chip years do not send a PCM.
- Email: no hardware shipping. Files go over email.
- Cable loan: I ship the kit to you; you ship it back when the window is done.
- International: extra return postage is added on the order form (USPS Priority or UPS Worldwide, usually about a week). Chips: Canada/Mexico $30, overseas $50. Flash PCMs: Canada/Mexico $35, overseas $65. Cable kits: Canada/Mexico $35, overseas $65.
After you order
Once you place an order, and I receive your PCM (or emailed tune image file) and payment (or just payment for chip orders), I will be able to begin work. Postal: one free retune (same setup) — you pay shipping both ways for a flash PCM; for chip years I mail you another chip. Email: up to three free log retunes. Cable: fine-tune during the rental window.
How to order
- Sign up Get a customer # so your contact info stays separate from each PCM/order.
- Place the order Log in with your # and password, choose type + method, describe the car.
- Pay & ship (or flash) You’ll get payment and shipping/flash instructions after the order is in. Chip years: you do not need to send me your PCM.
