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 1986-2002 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 / $80 OBDII / $85 LS1 for basic changes, or only $110 OBDI / $120 OBDII / $150 LS1 for power, MPG and/or auto transmssion tuning, or for your '86-'92 TPI/TBI or '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 1986-1995 PCMs, I can loan you an ALDL cable to data-log your vehicle while driving so that I can fine-tune it for you for one week: through email for the 1994-1995 LT1 PCM ($145), or with new chips sent through the mail for 1986-1993 TPI/TBI/LT1 PCM ($165).
