Lol. Knowing me who the hell knows. For the immediate future though 400ish whp sounds like plenty for me. Stage 2 it somewhere down the road probably."What you been up to?"

Wanna leave the exhaust stock as possible because most setups sound like ass in my opinion and are entirely too loud, so that will be a limiting factor for long term power for me.
