1998-2008 Pontiac Grand Prix GT GTP GXP 3.8 Supercharged 5.3 Mail Order Tune
Our mail order performance tuning generally results in a 10-14 horsepower increase and a 1-3 mpg improvement for stock vehicles, with potentially greater gains for modified ones. Additionally, customers often experience enhanced part-throttle response, improved drivability, and increased acceleration from a standstill. We can also tailor the tuning to accommodate any specific modifications you may have.
Just some of the changes we can do:
Fan 1 and 2 Temperature On and Off Change
90 second fan on at key-off (this feature activates when engine coolant is (Your Thermostat Temp) degrees or greater)
Change transmission type (4T60e,4T80e, Manual or non-electric auto)
Delete VATS
Change Axle Ratio
Change Tire Size
Remove speed limiter
Remove torque management - Torque abuse modes are modified to eliminate bog at launch
Remove unused engine codes (Leave in notes what you need turned off)
Emissions Removal "NOT FOR STREET" rear O2, Cat, EVAP, EGR.
Engine Swaps
Fueling modified for WOT (Wide Open Throttle) performance
Timing modified for WOT performance
Raised rev limiter
Raised shift points
