I installed the NGK TR55 and Thundervolts yesterday, and at first they were great. Then later in the day, something kinda made me mad so i drove pretty aggressive. I noticed it was harder to peel out. i dropped the clutch at 3.5k and as i shifted to 2nd (where it normally keeps spinnin), the tires caught and the RPM went hard down to around 4k and slowly dropped to 2.25k until i began to move forward normal again. Could this be related to the new plugs and wires and something i did wrong or is that normal and i just dont know it?
