Update: I just got my ECU flashed by Jerry from LET this weekend. The tune I got picked up 28whp on a diff c55 so its time to get back to the dyno and see how much of an approvment it is.

The car is a 2005 C55 AMG that has been blacked out w/ drop in K&Ns and some exhaust work.
Took the car to the track and it ran very well 13.3 @ 106
Also put it on the dyno and put down just over 301whp and 314wtq stock w/ K&N Filters only. With the Cat/Resonator delete I should have picked up 5-10 hp. New dyno numbers and 1/4 mile times are coming..
