Look at your complete intake & intercooler system and look for a restriction. What are the measurements of your frontmount?

The reason I say this is because a friend of mine bought my old turbo set-up from me and installed it on his 1g (2.0 w/2g pistons, Comp cams). Made good pump gas power at 18 psi until around 6500rpm, kept loosing power quickly after that. Since I was doing the tuning for him with DSMLink over the internet, I couldn't see his set-up. Fuel was good, 18 psi at the intake all the way to 7500rpm. We kept trying to figure out where the power was going for the longest time. I knew he had a front mount, but I couldn't remember what size. Finally I got him to put a boost gauge on each side of the front mount and make some runs. He found at 18 psi at the intake manifold he had a 1.5-2.0 psi restriction at the intercooler. Meaning his turbo was pumping more boost to keep the intake psi up. No need to look any further. Another front mount is on the way.
