You can have your PCM tuned for a very small price! If you are already a customer with me and have received your customer #, just fill out the form below and we'll go from there. Otherwise, please go to Customer Signup to begin the process.
Before entering your vehicle data, please choose your PCM's year and body-type, which type of tune you want, and the method of receiving it. Postal will involve you mailing your PCM to me (or me mailing you a new chip for 1992-1993), and Email will require you to have your own tuning software and cable (and chip burner and chips for the 1986-1993) to load the tune file I send. For Cable Loan, I send you a cable and software to reflash your PCM (for 1994-2005 LT1/LS1), and/or datalog your vehicle (1986-1995 TPI/TBI/LT1), so I can fine-tune it for you.
For information about the different tuning options listed below, visit the main Tuning Service page! Basically, the Basic Tune only covers simple changes like rear gears/tires, fan turn-on points, systems (EGR, VATS, etc.) disable, etc. For tuning to increase power/torque, MPG, or change auto transmission shift points, you will need the Power Tune.
I want to thank you again for getting me the tune that day. Made the next night a lot more fun with the manual trans in and the proper tune.
Car runs great, no check engine lights and the speedo is right on. No one expects a full size wagon to be that quick.
I know a few people looking to get a tune for their LT1s and you're the one I'm recommending.
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!
