I've been tuning a 2006 Trail Blazer SS, it has a comp 219/227 112 cam, headers and 46lb injectors. I tuned it for e85 and it runs good. Only weird thing is if we brake stall the truck most times is wont go into PE mode until the brake is let off, then it goes into pe real quick. Once in while it will go into pe stalling it and it launches allot harder so we would like it to do that every time. I believe I have all the pe tables set correctly ? Any ideas ?

Thanks!

 

What tuning software are you using? Can you post up the tune? I don't run a PE mode at all on my truck, I would rather have it that way. You would obviously have to tune it that way though.

 

0 everything out when it comes to kpa, and rpm requirements...also make sure u have the highest ramp in number. Then go to the cold table in power enrichment and make sure its not THAT high. the TPS percentage is the trigger once kpa and rpm is met. so once u have 0 kpa and 0 rpm (which is alwaus) and u step on the pedal lets say at 70%, ull enter PE

 

I will give that a try subeone. Thanks guys.
