thanks justin!!!! i received the x3 & filter on wednesday, so i installed a canned tune & it was great. no lag & very responsive. then this morning i installed the vmp filter & the 87 performance tune. wow!!!! i got startled pulling out of the driveway. it shot forward when i barely tapped the gas. it took some getting use to, but damn the power is sweet. i'll try the 87 mileage tune tomorrow for some freeway driving. can't wait to try the 91 perf tune.
anyone with a gt & no cai/tune, go with vmp. it's on sale for $439+shipping.
