Yeah, and with relatively high static compression and a big honkin' turbo you are going to have to keep a close eye on your spark advance. Depending on how good your pistons and cylinder head are at resisting detonation I'd put your timing at peak torque around "18-20 psi" in the 15 degrees ballpark.
