I'm completely new to efi tuning. Just starting to get my feet wet with hp tuners. So I've payed to have my car professionally tuned. Everything seems fine except for when I push in the clutch and return to idle/ cruise and return to throttle from deceleration the wideband will peg out and the car will run a little rough for a second and then clear right up. Trying to get a good idea of where to start and if a short lean spike is harming it?
