Yes 299 on a mustang dyno with Gen 3 intakes, Berk HFC and Stillen CBE w/stock tune.
Why? Is this because smoothing out intake flow will raise the A/F and possibly create a lean condition while un-corking the exhaust will create a rich ("safe") condition? Or is it that the ECU doesn't respond well without a tune to mods on the front half?

I honestly don't think a tune would be worth much (5whp?) if all was being done was correcting your A/F here.

Does the car surge or feel less smooth than before the mods?
