I've been having problems with the car running super rich so I finally made an appointment for a chassis dyno tune. Turns out my mail order tune sucked, it was running too rich. Dyno shop was able to fix it though, pulled 330rwhp and 326rwtq. Numbers were a little lower than I expected but I guess machine shop didn't port my heads as much as I thought they were. Oh well none the less it pulls like a raped ape. I love being able to drive it again.

 

What kind of dyno, that could also make a difference.

 

you should make around 350 rwhp with stock untuched heads with a cc306.

I notice your running a spec stage I clutch. Maybe it can't hold the power your making? I would think atleast 340rwhp in a M6 no?

 

So what did the mail order show in re A/F etc. and what did the Dyno shop wind up getting with their tune?

 

Air Fuel is roughly 12.8-13.1 after dyno. Dyno was a Dynojet. Its a brand new spec 1 too, wasn't broken in yet.

 

WTF?! 350 to the wheels with a cc306? Wow i need a cam job.

 

You need the supporting mods though. My #'s are in sig with bolt ons and 306.

 

My stock clutch has held up to the #'s in my sig for 6000 miles and about 30 runs in the 1/4.............I know I'm on borrowed time

 

cmking, did you get a flow sheet for your heads?

 

No flow sheet. When I did rebuild machinist said he would do a small port job and bull blend for $400. Apparently he did very little port work probably, more like just a bull blend.

 

even without port work u should be making close to 350

 

Is there an echo in here
