So I started a remote tune with PDX Tuning out of Portland, and we are tuning my E85/FP Green setup and I can not figure out why my logs are coming back so bad at idle. Cold start is really choppy with my A/F correction swinging all the way from -25 to +25. Once it warms up and does some learning it gets better but any time the fans kick on it gets choppy and searches for idle. He thinks it is a boost leak or maybe a fuel leak but I have gone over my pipes and pressure tested things over and over with no bad results. I am confused guys, can anyone help me out?
