LT1 Tuning Tips & Service!
Learn the basics of tuning your own '94/'95 LT1/L99 PCM, including timing, fuel curves and more; or just send your PCM to me for an inexpensive tune!
Now Burning Chips for '86-'93 F/Y-Bodies!
If you have a '86-'91 5.0/5.7L TBI/TPI Camaro or Corvette, '92-'93 Corvette LT1 PCM, or a '93 F-Body PCM, I am now able to offer you tuned chips for your vehicle. For TPI/LT1, it will require you to purchase a piggyback adapter from Moates.net to use the new chip with your stock PCM ($35), or solder in a new socket for TBI ($30). My pricing will be $55 for basic changes and $80 for power/MPG tuning, and both prices include free Priority Mail shipping!
Now Servicing 1996-1997 OBDII LT1s!
I am now able to tune your OBDII LT1/LT4 PCMs, and you will still not find lower pricing ($75 shipped for basic changes, or $100 for power tuning).
I will also be supporting the 1998-2005 LS1 as well (including trucks), please signup as a customer and contact me if interested in those!
Other PCMs
Do you have another pre-'93 chip-based PCM that you need tuned that is not listed here? I still may be able to tune it for you. Just contact me with a description of your setup and I'll let you know whether I can help you.
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!
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 1993-1997 OBDI/OBDII LT4/LT1/L99 PCMs.
This includes the Camaro Z28/SS, Firebird Formula and Trans Am, the Corvette, Impala SS, Fleetwood, and the Caprice and 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 LT1 PCM for tuning, for just $60 OBDI / $75 OBDII for basic changes, or only $85 OBDI / $100 OBDII for power, MPG and/or auto transmssion tuning, or for your '92-'93 LT1 have me mail you a new tuned chip for $55 or $80. All prices include free 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 LT1 PCM image, for only $60 for OBDI or just $75 for OBDII, including three free fine-tunes!
Tune Testimonials
1994 Caprice
I have been driving that 4.3L L99 Caprice car you tuned and my gas mileage is way, way better. I am actually getting over 30mpg on the highway now. My last tank average was at 29mpg. The power level is about the same but the mileage is incredible for a 4,000 plus pound car.
