I currently have full exhaust, drop in k/n, and power fc with base maps with alittle fuel added via pimvolt menu in the low/mid rpm range. The car runs fine and O2 seems rich (i thought it would be lean with a mp).
Here is the question: Since i am finally adding a cold air intake do i need to have the power fc tuned? Will tuning the power fc capture some HP? I am sure that i will have dave at kdr tune it but does anyone have any first hand experience with dave duning their power fc. what where the hp results?
