Been trying to polish up a tune for a 99 Silverado. Hoping to get some suggestions on what you see wrong.

99 Silverado- 02 PCM, 02 Injectors, Ultimate PD Air intake, PV Catback Exhaust, Trailblazer Stall, with Shift Kit.

Truck Runs Ok, feels like ther is more there. I do not have any logs at this time, but can definitley get some for you..


Any help you guys could provide would be greatly appreciated.


Thanks for looking..
