This is a very sick set up!!!! Any nice gains?. How much did the M370 cost
you ? And besides the Motordyne test pipes did you have anything else or
did you just tune with the TP and Catback
I dont remember what I paid for it because I ended up getting a package deal. I have the motordyne exhaust, test pipes, intake manifold and stillen gen3 intakes. I gained about 25hp after tune.
