TBI/TPI/LT1/LS1 Tuning Tips & Service!
Learn the basics of tuning your own TBI/TPI/LT1/LS1 PCM, including timing, fuel curves and more; or just send your PCM to me for an inexpensive tune!
Are You Ready to Tune?
This website is dedicated to helping you learn how to tune your own LT1 car computer (PCM), using the popular and inexpensive TunerCat software as the model.
Start with the basics, like removing the skip-shift for you six-speed owners, or accommodating for the larger wheels or different rear gear ratios you've installed.
Then we'll progress to altering the timing and fuel curves, to get better throttle response, torque, and even MPG! Click Free Tips to see what I have so far! Much of it can be applied to other engine/PCM types, including TPI and LS1.
No Interest in DIY, or Only One-Time Changes?
If you don't have the time, money or desire to do this on your own, but would still like some changes made to your PCM, I also offer a very inexpensive tuning service for the 1986-2003 OBDI/OBDII TBI/TPI/LT4/LT1/L99/LS1 PCMs.
This includes the Camaro IROC/Z28/SS, Firebird Formula and Trans Am, Corvette, Chevy Caprice & Impala SS, Cadillac Fleetwood, and Buick Roadmaster (including the 4.3L L99 engines)! Just click the Get Tuned! button above to learn more!
Postal or Email Tuning
If you have no ability to tune yourself, my main service allows you to postal mail me your PCM for tuning, for just $70 OBDI LT1 / $80 OBDII LT1 / $85 LS1 for basic changes, or only $110 OBDI LT1 / $120 OBDII LT1 / $150 LS1 for power, MPG and/or auto transmssion tuning, or for your '92-'93 LT1, have me mail you a new tuned chip for $60 or $100. All prices include free USPS Priority Mail return shipping and one free retune!
But, if you have your own tuning software, and are looking for help or a place to start, I also offer tuning via email, using your own PCM image, for only $70 OBDI / $85 OBDII / $100 LS1, including three free fine-tunes!
Lastly, for 1994-2003 flash-based PCMs, I can loan you a kit to load my tunes yourself as well as data-log your vehicle while driving, so that I can tune it completely through email, for one week: 1986-1993 TPI/TBI/LT1 PCM ($185), 1994-1995 LT1 PCM ($145), 1996-1997 LT1 PCM ($170), and 1997-2003 LS1/Vortec PCM ($200).
Tune Testimonials
1994 Caprice Classic LS
At first I didn't think my L99 was even worth getting a tune, because it's only a 4.3L version of the LT1, and there's no replacement for displacement. But, in the end I decided it was worth a shot, because my car had so many problems and always so weak, I felt it deserved a shot to impress before I just replaced the motor.
I heard so much about Solomon's tunes, that I felt he would be the right person to tune the car. I had been in contact with him for a while prior to ordering the tune, kind of preparing for it and stuff. Then just a couple days ago I felt the time was right. Ordered the tune, and the first tune came in nearly only a couple hours later in an email. I loaded the tune and immediately felt a difference. Throttle response increased, shift points were much nicer and aggressive, including the firmness.
I had the timing increased even more manually, removing all spark retard from my PCM (as I have a faulty knock sensor circuit), and going "old school" on the timing, now it's zero spark retard, very advanced, and running top notch.
Dude, you are the BEST. That car pulled out like my friend's LT1 camaro, which is oddly surprising, because I never knew the L99 could do so well. I pulled onto the highway and didn't even gun it, and went from 0 to 55 in no more than 4 seconds...
AWESOME tune man! Thank you so much. Best 65 bucks ever spent on this car bar none.
