You'd probably be "ok" to peak there on occasion, but I wouldn't hold the revs.
Just curious was he using Greg's Oil pump piece?

I wouldn't bother. Unless you have head work there wont be any beneficial power past 6800rpms. The nice thing is that you have those schricks which make nice power up until then. It's the perfect setup for any stock internal n/a m54.

Yeah for a stock m54 it would be a waste but with the shricks would you agree it would be worth it and I would be making power at 7k

Yea I mean you'll def make power til 7 but the power peaks just a tad under that mainly because the head cant flow anymore air. But sure, with a tune, 7k will be fine for the street. I would have the ATI Damper and upgraded OPN too just to be safe.

Nice I really need a tune to top off my headers and cams.. Haven't been interested in pulleys because I hear gains are negligible.. I really wanna upgrade my clutch and brakes .. My goal is to break 240 whp and end up at 250whp
