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.

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

If you remove the 20% CF from altitude you will see that it is only using fuel for ~420whp so the 1000's and a single wally makes sense.

^This.

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.
