VCI update # 1020956 ??

[superC]

I took my redline in the other day because it seemed to be running lean, and it was, system lean code showed up, they told me they called up GM and GM told them that there was a ECM update for the stage 2 tune . they installed update and , any idea what the update does ? my car doesnt seem to pull as hard?? any ideas?

i dont know as much as anyone on here im sure but if you where runnning lean then i would assume u had some extra power coming in because of it somewhere in the powerband and now that they made it ritcher u lost some power my 2 cents

What code where you throwing before? Because if you have a aftermarket intake it could cause the code to come up

makes scense ... which leads me to believe if that was the case they prob just reflahsed the ECM duno why they said there was a new update to the stage II for the ECM unless that has something to do with it?

There is a update for the stage flash i think every month , there is alot of different versions but i never heard of a one of the flash that causes lean code to come up.
