Ironically enough we had 3 tibs on the dyno today. They showed up with a BMW club for some reason. The heavily modded one pulled down 180hp and 180tq. The lighter moded one did 160 +. The 3rd one was supercharged with 4 psi. He did 193. It turns out that the top end sucks because of the design of the upper intake manifold. Or so those guys told me.
