hello everyone, my 2011 chevy cruze LS 1.8L auto 78,000 miles, seems to make a strange chirping noise while accelerating at low rpms. For example once my car shifts into 3 gear and I am traveling about 15mph and I accelerate further just enough so that the car doeskin down shift it'll make that...

The title says it all. I just replaced my plugs with new plugs at .035, first time with the K&N filter. After finishing a tank of 87 octane and lack luster MPG, I filled up with 93 octane and hold on to your seats!!!! Never saw this much power b4 without a tune! Hoping I don't kill the MPG...

Today I finally broke down and gapped the plugs to .035" I have had a Trifecta tune for awhile now with no problems. Soon as I pulled out of the garage and went WOT in 2nd, I have HUGE surges, anything over about 17 psi and I'm getting horrible power surges, so i know my gas light had been on...
