BPU DYNO...check out my running RICH AS HELL supra

I dyno'ed yesterday at AAM.
I'd like some of you tech guys to let me know what you think.
The chart has Max power 380RWHP (378.8) and it also shows the air fuel (wide band O2)

Here's what I used:

94 TT 6spd
93 pump gas
RPS stage III clutch w/ lightened flywheel
HKS intake/ SSBOV
AEM Cam Gear -4 exhaust
BCC
RMM downpipe
HKS exhaust
MBC
Greddy 60mm Boost guage....ONLY HIT 1.1 BAR ????

The guys at AAM said I could get a good 20-30RWHP just by adding and tunning a S-AFC ?????????

I NEED 400 to the wheels. The S-AFC will do that, right? Also, I don't need the VPC, I can just hook up the S-AFC and lean it out, right?

Don't understand the 1.1 bar part,why weren't you able to boost more and also why didn't they look into that problem :mad: Did you use the race gas ? Also from your A/F ratio curve i see you are running way too rich (around 10.7 at 4800 and then a spike to 11.2 and then back to below 10.0:1 which i think could cause you to loose some power. Ideally your A/F ratio curve should have stayed linear and also between 11.5:1-12.2:1.Someone correct me if i'm wrong :D

1.1 Bar is not much... I hit 0.9 Bar on first turbo, on both I can hit 2 Bar. Now I have set it to 1.4 Bar. Try to set higher boost and you will get 400 rwhp - no problem.

If you can not make boost higher with your mbc than try to tighten your BOV - could make boost leak. You should hit 1.4 Bar.

Good luck man:)

I used 93 octane pump gas.
The 1.1 Bar :( I'm going to look into. I didn't want to pay them any more than I allready did to tune (see why I only hit 1.1 bar). It cost $120 for 2 pulls w/ the wideband O2:mad:

So guys....my car is running WAY rich, right.

All I have to do is install the S-AFC and then tune, correct?
