It's ENTIRELY possible that you HAVE ENOUGH fuel. Remember my post above when I said that the Garrett T03/04E is a big turbo. More CFM's not only mean a need for more fuel, it means that it's pushing out MORE power. I'm guessing at 10 psi, you're really close to 300 hp (at the flywheel) if not more. That means, you're reaching the upper limits of what our engines can handle, with adequate fuel or not. That's the difference with our engines and the 4g63 engine: our stock engine internals can handle stock about 50-75 less HP than theirs. If someone tried to hold 375 HP and up with a 4g63 engine, it's very likely they may blow something up too.

Like others have posted...10 psi in a Super 16g may reach close to 275 horses, but a bigger T03/04E turbo may reach something closer to 300 horses.
