Don't know the duty cycle, but I guess the injectors are big enough.

My engine has a very strong midrange due to the full-race twin scroll gt35 kit. It seems to need a lot of fuel in that range.

Testing with 29/30psi on pump fuel, the walbro ran out of fuel at 3800rpms, producing 445 ft-lbs of torque at that point. The max torque should come around 4200rpm.
On E85 that could be a nice boost-level, but would need a lot of fuel.

I (or rather, the tuner) lowered the boost to 21psi and tuned it there. Giving 404 ft-lbs of torque at 4200rpm. Something else is holding me back at high rpm though, so I have no bragging rights in the high-horsepower community :/
