Now I could also get an additional 40-50 hp by moving to the east coast down to sea level and running 93 OCT.
How is that meth kit along with the procede. Any issues? Would the longevity of the motor be compromised running meth? I'm trading my FBO+Meth 135 and since i'll have shiv's PWM kit laying around i figured why not try it on the M along with the tune. I was very happy with it on the N54, thing was a monster.
