[QUOTE="Cobriscus, post: 448005, member: 23123"] You said the fuel pump is fine/replaced/tested. The engine demand under load (in gear) would be greater than in park/neutral, so it would make sense that it doesn't bog at WOT when there is no load. Are you running an aftermarket throttle relay (Pedal Commander)? If yes, unhook it or turn it off to see if it is causing the issue. If no, the throttle position sensor could be giving an incorrect signal. The engine will get the incorrect spark/fuel mix from the computer, thinking the throttle position is more or less than it really is. [/QUOTE]
