What are the software tuning options for catless exhaust manifold? There is one from AA, but it is a bit pricey for $500. Any other ways to tell the car to take advantage of better breathing?

The only tuner currently giving the N52 attention seems to be 22RPD

I spoke to Bob like 3 weeks ago - he was expanding his shop. Try calling.
