I have run the ECU diagnostic, its for the fuel temp sensor circuit, and I can't find out exactly whats wrong, Consult shows the fuel temp just fine unless it could still malfunction yet show the temperature.(I think it was mid 100 degrees like 150 I'll check tomorrow) Other than that there are no codes. The boost controller, I'll solve as soon as I sell my current and by another (whether manual or a different electronic). As far as boost leak goes the only real place I can think is the IACV (which I need to take apart clean and refurbish) or the plenum gasket. I do have a very good shop fairly close that can definatly give me a nice tune. As far as piggyback/ standalone goes, what is there besides AEM? I understand the power commander FC is in beginning stages but does anyone have a comment on the Greddy's or the HKS? Also what are you running as far as a BC goes Seedy, boost jets?
