Just installed a 95 eprom with stage 3 chip from dsm chips in my 97 gst to compesate for 680s. When i start the car cold it runs like it is not getting gas and stalls. When i start it up again it idle surges a lot till it warms up then runs fine. I have the safc zeroed out. I took the car for a drive and it will hold 10 lbs of boost ok. Had a cel p505 cleared code and cleaned isc motor also checked resistance 28 ohms. Does not seem to be any vacuum leaks what could be causing the surge. Car has a rebuilt motor not broke in yet. When i rev the car in nutral it goes to 3500 the feels like its is missing and wont steady rev up but when i drive it its fine.
Should i set the safc to 30 low and 80 high or leave it at zero?
I am getting ready to order a wideband to help tune what kind should i get?
Is there any body in carroll county md that can help me tune it.
