Well I went to the dyno today and she pulled 306rwhp
at around 10psi and at around 13.5/14psi she pulled 326 both at 7400 rpm (didnt rev farther, scared). The wide band read 8:1 for most boost and around 8.5:1 7000 on. The ignition didnt like 16psi. Way rich, how much power do you think there is in there raising the air fuel ratio to 10:1??
This is a Ray Locheed map so any of you with one are probably running rich too.
Time to get a datalogit and go back to the dyno.
Thanks
Billy

Johnny you were just about right on.

dude 8:1...man that's way way rich...

some power left in that baby..you need some wideband tuning with the PFC...not sure how much more you could get...but I'd like to guess 20-25 more atleast...I' like to say alot more...but I have no experience with ever running that rich

You are running extremely too rich.

You'd like to be around 10.8 on the high boost end (15psi). Aim for 11.

No wonder you had problems on high rpm with ignition. The fuel alone would probably cause it to break up a bit.

You have some power to tune out with the fuel.

Datalog a few runs with the wideband next time and lean out that fuel.

Good luck,

Dude, at 8:1 you must be getting about 4mpg. And you might want to check your plugs and make sure they're not fouled.

billyrohm

It only goes to 8:1 under boost. During the pre boost it's fine. I dont think the plugs are fouled because the plugs are a couple months old and just pulled 326rwhp. Also when I tried running 16psi it pulled around 300rwhp at 5500rpm. Gotta pull out a little fuel

SPOautos

yea, thats bad rich, you need to be around 11 - 11.2 a/f.

You had awsome #'s considering how rich you were.

Later,

I'm sure with tuning you'll be at 360 rwhp at 10.8-11.0 a/f - that's great numbers for running so rich and not having a streetport.

20rwhp from going from 10 psi to 14 psi ?????????????????????????????????????????????????? ???????????????????????????
