Did your fuel pump run out of flow? I think a Wally 450 is what you should be running.

Power curve looks like single scroll.

Surprised it made that much on a single walbro 255.

Thanx guys, yes with the new SS housing it felt great. I couldn't believe the difference vs 93. I wish the pump had E85 to see the number but I'm happy with my tuner!
I rewire my 255 Walbro so it constantly get 14 volts and engine didn't go lean during the pull. They say single Walbro is good up to 550 hp

I think your tuner dropped the boost 5500-7000 because your 255 could not support the demand at higher boost levels.
With a bigger fuel pump, you could get maybe another 30whp at around 6300rpm.

That's on gasoline, and still a maybe depending on boost. When I first got my red, the walbro 255 was done at 26-27psi, 420whp.

Did you have 1800cc injectors too? It's still surprising it made this much. I wonder what the AFR is 5000-7500 RPM

Injector size doesn't really help a fuel pump flow more fuel...

Peak boost was 31 psi and went down to 28 and then going up. but my AFR 11.5 to 12 at WOT
The tuner didn't lower the boost he tried to maintain as much boost. There were no count of knock
Next move I will change my injectors to 1300cc high Z, the low impedance made it hard to tune but not the greatest for street driving
