That doesn't seem like a very strong fuel system for having such a large turbo and running Ethanol. What do your IDC's look like?
Sick numbers btw, what kind of elevation are you at?
Have fun with it.

Power was holding up good untilled 7100 Rpms your power starts to fall of looks like your bov is bad..
is this dyno read high? Cuz u only have 1 walbro and e85 fuel, i dont think it can go past 500. Very tastefully mods thou.
or take a look at a/f it richens up, the lines are almost identical from a/f to hp. what ever your a/f does you will see a direct reflection of that in your hp and torque curves

Tobz shop uses 1.20 CF, so these numbers are basically dynojet numbers.

Hell on my BBK Full my 1200's are JUST doing the job. For that turbo you need bigger injectors and at least an inline pump to work in tandem with the Walbro.
