Rode my M8 with SLP performance package in Cook City Monday and Tuesday. My sled ran awesome!!! The pipe is a good gain but the porting really wakes up the motor.
I used their fuel map for the PC V and the sled was pull and go both days, I didn't touch a thing.
I did my own clutching setup and rpms were right on and the motor pulled hard. Running a little heavier clutch setup and the rpm's were still holding 8050 to 8150.
Got to say I am very pleased with the way the setup turned out. Would reccomend this setup to anyone.
Mind sharing what clutching your running?
