I'm still having a hard time deciding how to setup my PE parameters on my 2012 Impala (3.6L LFX). I guess I'm not quire clear on the pros & cons of PE mode. In stock form, PE mode is not enabled until 95% torque and 90% pedal (until 5120rpm, where it starts enbling a little earlier @ 83% pedal and slightly lower from there on).
I guess I'm just looking for a little input as to when and why I'd want to enable PE. Being that the stock tune doesn't enable it until 90% pedal for the most part, is there any reason/advantage to enabling it earlier? Any disadvantages?
I know that PE mode "richens" the fuel mixture, but again, not quite sure how to decide when to have it enabled.
Thoughts/opinions?
Thank you!
