Re: What to do to get 300 rwhp on a Mach 1

Just got past the 300 mark. I dynoed 263whp and 281wtq dead stock. I added the slp longtube headers, slp catted x and slp loudmouth 2s and put down 306whp and 318wtq with nothing else on a stock tune. I'm hoping with the addition of a jlt rai, php spacer and tune i could get up to maybe 325-330whp. My a/f ratio was still on the rich side even with the full exhaust.
