Okay, i'm definitly planning on getting a tune (just not sure when yet). If I left the rear O2s disconnected without simulators, will the engine run right? I know the SES light will be on...I thought I read that when the SES light is on the computer goes into a "safe" mode or something, and does not run up to its potential.
I don't want to to spend money on O2 sims if i'm just going to get them tuned out when i get a tune in the future....
