I all I have a traillblazer ss with a magnacharger on it and I just put the magnagharger tune file in it...
My truck is working great but I have a small problem with it.the problem is that when I'm at full throttle the truck is pulling real hard until 4500 to 5500rpm and than stop... the fuel injectors just shut down from 15ms pulse to only 2-3ms and the engine stay at that rpm until I let off the throttle. I disabled the TCS completely and it dosent work ether... It seam like an engine protection of some kind I also upped the MAF Flow vs RPM and vs volt of about 50% and it dident do anything. I also tried to remove all the the cutoff of the truck (all!!!) and it still dose that.
It also dose that in neutral...
I have tried every thing I know I dont know what to do whit this...
any one have an idea?
PS: I'm also working with Drew Zimmer from the magnacharger Calibration dep and as of now he did not found the problem...
