Does yours ever surge? I just put my stock inj back in and ran the car on a stock tune and it still seemed to run "rough". I am not sure how it is supposed to sound anymore though. What are you mods Kent? Was your car worse before you started VE/Maff tuning. Also is there a chance you could pm me your IFR table, if you are using pt, or if not that could I pm you mine so you can compare them and make sure I am close to yours. I just did the math method 35/65= whatever it is.
