more bolt ons but slower times any suggestions...
2008 e63 only k&n filters & row airboxes and pilot super sports made 8.01 et 1/8th mile . Now it has weistec ecu tune, nitto drag radials, and american racing headers couldnt do better than 7.88 what the hell. I feel grinding,slipping feel in gas pedal sometimes at 6/7000 rpms could it be a bad torque converter or tranny issue. Feels way faster on the street and track with headers but numbers dont add up any help thanks.

Isn't a 7.88 faster than an 8.01? I don't see how your times are slower.
You don't mention track conditions or the weather. Both can make a big difference in times. Any before/after dyno numbers?
These cars are throttle by wire so any grinding/slipping you're feeling is probably in your head.

I would have expected a slightly better improvement in times considering the tune, drags, and headers. Any before and after dyno results with that tune to verify that its done anything at all?
