    Weird question here,
    earlier this spring I installed a VMP gen 2r 2.3 on my 2013 GT. It worked great, pulled super hard and would break traction in third with 3.31 gears and even an extra passenger. Recently however, it seems down on power. I passed it off that the hot humid Minnesota summer was holding it back, but it was a pretty cool morning today, about 54 degrees, and when I romped on it in second it wouldn't even spin the tires. Something really seems off. I haven't pulled a plug or done a compression check yet.
    It's got a fresh clutch last year and barely have 3k miles with the blower, any ideas? No check engine lights or anything.

    Look and see if it's throwing any codes (not all trip the CEL), or datalog and see what your tuner thinks. The computer should help point you somewhere.

    If it lost that much power I would datalog as suggested. I'd also replace the plugs and do a compression test, sounds like it's down on a lot of power.
