AA headers n54 manifold and TB

@thomasvancil · 12-19-2018, 05:57 PM

Im about to get some AA catless headers and n54 manifold w/ throttle body. Any one else running this setup, what power gains am I looking to get before and after a tune? Also if anyone knows a good tuner around the Norfolk VA area lemme know!

BPC has done a lot of these combos and would probably be the best bet for a good tune....you may need to drive there though, not sure they have an off the shelf tune for your specific combo (not sure what else you have on the car).

It will run too lean without a tune, but you can make 245whp+ with that combo...you'll need a custom intake and PVC to make it work, and you will lose a bunch of torque. Consider the MILVS at the same time (or before) you get your tune.
