425 Simple Horsepower?

Will an excellent tune and a Callaway Honker with a Magnaflow Magnapak straight thru exhaust give my 07 A6 425 flywheel horsepower and maybe 15 extra rwhp? Its otherwise stock, 2500 miles young.

i think that is reasonable. tune alone can net you 10rwhp and i am sure the honker and exhaust will get you another 10rwhp.

You probably already have close to that with a tune.

Tune being performed as we speak, that was the first pull. Will post results as soon as it is finished ~ 3-4 hours or so. I still haven't installed a CAI, though I am probably going with the Callaway Honker. Cheers.
