I do all my tuning on ls platform vehicles and these cobalts really have very few tables you can edit in comparison. I was curious to see anyone elses hpt files for a stock lsj sc that they have messed with. i would like to check some comparisons.
Also i have read many times that the stock tune is pig rich. I ran the eq ratio numbers on mine and they all hovered around 11.8 which seems pretty decent. I perfer 12.2 with forced induction but i was thinking when everyone was saying pig rich i figures 10's. Regardless stock idc is 96%. boo!!!!!

 

anyone?

 

I'm not sure about the stock tune, but I know GM's staged tune commands 10.8 before COT or any other adders are on during WOT.

that may make more sense. you really can't command 10.8 with stock injectors or your idc's are over 100.
