The car feels strong (on 4.02 Cobb AP 2+ maps), but there is a pronounced whistle, and at <1000 rpms it is vibrating significantly (like I feel it in my seat and the dash is creaking). Mr.5 intake, FMIC, and DP were just done, didn't get to log it yet but I read codes when I got home and didn't see anything. I am running the BMS DP Fix too if that matters. This doesn't feel normal at all - there is no noise like DPs are hitting anything, just a lot of vibration, and the whistling is beyond turbo whine (it's present even at 1500 rpm, accel and decel). I do have Forge DVs on (been on for months) with yellow springs.
Any thoughts? I'll run it hard tonight and get some logs.
