Ok so i have a boosted built gsr with precesion 1000cc injectors tuned on ectune with a demon installed. Just got car back on road it sat for the last few months before installing a new clutch and hydro conversion. Btw hush22 kit works great. Well the car is on a tune from earlier this year probably start of summer and im planning on getting a retune soon.the car runs and drives great with good afrs except just recently about aweek worth of driving with no issues started having an idle issue. It will go totally rich at idle ike 10.0 on my aem wideband and sit between that and ---before slowly working up to maybe 11. Any ideas?

have you checked the fuel pressure regulator? diaphram could be messed up

My cars afr was perfect on the dyno but then when I go it on the street afr was **** until I hit boost I would get it tuned in the dyno and have your tuner adjust afr when driving normal and at idle off the dyno

Why would afr be crap only af idle if it was fpr?
