HPT Vs. Stage2

[05RedLinin]

how much of an impovement will it make?

[thedubsack85]

if you allready have the stage 2 tune and pulley and injector's it will help sort out the AFR using HPT. if on stock pulley,injector's and tune it's not a big gain. if still under warrenty go stage 2 and have someone work the kink's out. it will net you atleast 10 WHP and should only cost 50 to have someone tune it.

or you could just HPT the stg2 tune onto your car

well thats what i mean cuz i already have the GM stage2, and i wanted to get a HPT for it but i was wondering what impovements it will make over the factory stage2 tune....also the only additions to the stage2 ill be making are a 2.85 pulley, K&N CAI, GM exhaust manifold and zzp DP.

Well my car is a strange example but I went from 208 WHP with stage 2 and a 2.8 to 235 with a HP tune. But it ran low from the start and still barely made common stage 2 HP with a professional tune.

HP Tuners, on its own, will not make an improvement. Tuning the car will.

But you don't know how, or don't have access to someone who does... it'd be a waste of money.

Given your mods list, you could definitely benefit from a custom tune.
