If that car has a factory airbox (assumed from the comment 'drop-in K&N') check logs for a sharp drop in baro at 7K. If so drill some 1" holes in the airbox lid. The factory boys are smart and have 2 power-limiting engine savers- carefully calculated inlet area to airbox, and the factory BCS that closes the vent at ~25 PSI.
yep it does have stock box with K&N drop in.
