if they tuned it for 358whp, stick with that.

if you want more power you are going to have to:

a) get better gas
b) get an external wastegate ($$$)
c) (a) and (b)

harman motive is a competant tuner. dont try to chase extra horsepower out of an existing setup that doesnt like the added power.

and btw, please dont capitalize the first letter of every word. its rather annoying. thanks.

Lose the header... could be worth 15+whp to go back to stock.

Isn't the SR55 the replacement for the Sr50? If yes, then you are within a couple Hp of were you should be.

How does it drive? Also how much boost are you running?
