Thanks Good option, Donsnt sound like anyone's bought the tunnuin software and self tuning their H3? wonder how difficult the tune really is.furl curves and timing mostly

 

It takes time and experience in tuning a vehicle, there is more to it than just messing with Fuel and Timing tables. I been tuning Mitsubishi (Lancer Evolution) for 4 years now, and I'll tell you no vehicle is the same...

I might soon get the Software & Cables (HP Tuners). The only thing stopping me is, cause I don't use the Hummer that much...

Goodluck!

 

After 3 attempts by PCM4less im back to stock ECM with Jet chip, Again it pulls stronger and smoother, Not perfect but much better. I will try custom tune at some point, theres a little more there.They refunded my coin. great service
