hey i have a 4.3L silverado 02' my buddy jsut bought hptuners and we were gonna use 2 credits on my truck to give it some better shift points and what not. home much faster do you think it will make it??? maybe some tips on things to change??? i want a quick of the jump truck i dont race much but when i do its like from a stop light and i would like to be able to get a jump on a guy. dont tell me i need a biger engine i know that. i want to be a fast 4.3L though. give me some help guys. thx

 

some basic stuff would be:

turning off the "abuse mode"

reduce torque management by about 50%

lower full throttle from 94% to 90% that way the full throttle tables kick in faster

not sure what redline is on 4.3L but bump shift points to about 400rpm below max rpm for the motor (example: max rpm is 6500rpm for ls1, so we usually set them to about 6000-6100rpm)

and maybe just some basic fuel table tuning

we did this on several cars and the results were awesome
