#1
Hypertech model 390302 Power Programmer III, for 1999 only (updated to rev 6.11.4). Tunes 4.8, 5.3, and 6.0. Total cost, shipped to your door, $125. PM me!
Hypertech Power Tuning:
Tunes the engine for maximum power and performance, plus potential gas mileage improvements.
Engine Rev Limiter
Extends the engines RPM range for a wider power band
Transmission Shift Points
Optimizes shift points by speed and RPM for maximum acceleration
Transmission Shift Firmness
Firmer full-throttle gear changes for faster acceleration
Top-Speed Limiter
Allows the vehicle's top speed to be matched to the speed rating of factory approved high-performance tires
Speedometer/Odometer Correction
Automatically corrects speedometer and odometer readings with non-stock tire sizes and/or non-stock rear-end gear ratios
I sold the truck, and the buyer did not want the mods.
