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!
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.
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!
If you have no ability to tune yourself, my main service allows you to postal mail me your PCM for tuning, for just $85 OBDI LT1 / $90 OBDII LT1 / $100 LS1 for basic changes, or only $165 OBDI LT1 / $175 OBDII LT1 / $185 LS1 for power, MPG and/or auto transmssion tuning, or for your '92-'93 LT1, have me mail you a new tuned chip for $75 or $125. 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 $120 OBDI / $125 OBDII / $135 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 ($215), 1994-1995 LT1 PCM ($215), 1996-1997 LT1 PCM ($225), and 1997-2003 LS1/Vortec PCM ($250).
Solomon did a great job on my 1997 SS.
He has taken the time to help me with several problems with fine-tuning the PCM, on top of helping with other running issues.
He is very afforable, and customer service is A+!
If you send me emails from an @aol.com, @gmail.com or @hotmail.com address, or signup and/or place orders, but do not receive a reply from me or emails from my website, please do not think I am ignoring you! Lately, those email providers are randomly blocking emails from my servers. If you are on Facebook, like my page and contact me from there to ensure I've received your message and request a reply on there. Thank you for your understanding!
Do you need a good tune, but cannot afford the down-time of mailing your PCM to me? Do you not have any interest in long-term tuning where you would need to buy your own equipment and tuning software? Now I can loan you one of my tuning kits to allow me to fine-tune your 1986-2003 PCM to match your individual setup, without you needing to send me your PCM. No more downtime, and a fully tuned vehicle!
