It looks like most reputable tuning shops can just do a non-piggy back tune pretty easy.

It seems a lot of guys are also replacing the resonator/cats for a louder exhaust and more flow.

This engine should easily be able to make 750+ at the crank if it can breath.

Im trying to get back to my tuned RS7 typer power.

Ultimately, I will probably just drop it off at a reputable tuning shop and let them swing for the fences.
