Ok my car is still stock other than a lid and K&N and dynoed 310/340 and it is an A4. I am going to put on a new MAF, exhaust, under drive pully, and have it tuned.

Don't waste your money on the MAF, stock one good for 450-500 HP. And I hope your exhaust includes LT headers. If so with all that you could see numbers around 326-335 HP

I second the no Maf. He's right, its a waste of money. Now headers, free flowing exhaust and pulley you would be atleast 330 if not close to 340. If your just going catback don't bother with the tuning. Save your tuning for headers and cam, etc..

I wouldnt spend my money a MAF, just save it for a stall.
