Its most likely because he went with the FAST 102mm Throttle body, I noticed the small convolute(sp) that they built in to help with part throttle driveability. The cheaper versions don't take this into consideration and I think its why people may have a little more work to do.

Exactly, not just 20 hp at peak. I mean the LSXRT is a good flowing intake but I don't see enough over the stock 90 setup on the nnbs. Atleast the stock 90 added over the entire range both on torque and hp.
