Fouled spark plugs or your fuel pump. If you have used any gas additive at all octane boost, cleaner, race gas any of these will foul your plugs and cause your car to miss at WOT in higher gears and go into limp mode. If that is not it your fuel pump is probably on its way out.

Removing it wouldn't be a bad idea. I bet it's your hpfp.

What other mods are on your car?
Was the JB3 installed correctly? Contact Terry via email or call him, or even go over to N54tech.com. Something does not sound right. Good luck |

I found a broken vacuum hose that was going to the back wastegate solenoid.
