One is kellys he's destroked with reverse manifold efr7670 and his hits powerband ~4K and rides that baby to redline 8k.

What are you using for boost control? Potential the wastegate is blowing open? I cannot understand how short your powerband is.

I'm having my doubts about the turbo as well, my tuner has a Tial .63 exhaust housing that I am setting my eyes on. Just get hold of a up pipe w/ wastegate and that's probably my first attempt at coaxing this turbo to life earlier.

I am running a fuel called "Podium" over here, premium pump fuel, supposed to be pretty decent, 98 octane in theory.

I'm gonna check out those turbos, thanks!

I am running a Grimmspeed Boost Control Solenoid, braided lines.

That seems to be in order, boost is maintained throughout, I've looked alot at the gauges in various conditions. It only pulls once the wastegate opens tho. My first car with fmic and a first with this turbo, so, I don't have much of a reference.

I guess stretching the limit to 8k would also help, but, I wasn't really planning on fiddling with that because of reliability.

Thanks for the input!
