No, 400RWHP with modifications .

You have to tune the WUR and fuel head with an LM1 or on a dyno.
The purpose is to smooth out and optimise the A/F ratios throughout the rpm range. There are a few different ways this is approached. As you add power you will get to the point where the A/F ratio can no longer be adjusted to stay under 12.2:1 on boost. At that point you have to adjust the flow at the fuel head. When that is maxed you get the hi-flo iA head. When that is maxed you go EFI.

I always recomment getting an A/F graph of what you have before you buy any parts. You may not need any parts, just some tuning of what you have.
