TPiS, Inc.

TPIS EFI Tuning

We offer custom programmed chips for 85-93 Corvette, Camaro, Firebird, and street rod applications using the Tuned Port or LT1 system. We also custom program the GM flash ECM for the 94-97 LT1, and the entire LS1 and LS2 based formats from 97-08. For the flash computers you must send your computer to us for recalibration, but for the early chipped computers we just send out a new chip. We can configure a program that will run a stock engine with emissions and vehicle anti-theft deleted for a street rod application all the way to a fully customized program to control a 500+ horsepower drag race engine. Just call us with your specs. Pricing is as follows.

Level 1: Stock program with VATS and emissions delete for street rod ............$175.00
Level 2: Performance tune for stock engine (can also include Level 1 mods) ....$275.00
Level 3: Lots of bolt-ons, throttle body, exhaust, etc. ........................................$375.00
Level 4: Aftermarket intake, MiniRam, cam, & all bolt-ons ...............................$475.00
