Having a similar problem right now. IATs below ambient so pump is working. Now increase in IAT under acceleration so I'm guessing I'm not building boost. Usually when this happens the supercharger belt is off. It's fine. Clutch looks fine too. I'll log MAP tomorrow and report back.

Logged boost. It was atmospheric pressure. Battery disconnect solved the problem. No fault codes stored.

After a little over a month or so of the power loss issue My car eventually developed a misfire/studder at 4k rpm & higher.. Plugs & #8 coil fixed my problem I'm pretty sure!

Do you know when and if both fuel sender/pumps in the gas tank have been changed?
Those can cause big problems if they are not operating correctly.
Also you can call Cory@kleemann for ideas....he gives GREAT customer support!
Good luck!

I agree with worth the wait. Sounds like your fuel pump is starting to die on you. Just fyi our cars have two fuel pumps if one dies the car will drive fine around town but under WOT you'll start the engine (usually cylinder one) check your fuel pressure (under your air box next to cylinder one (front passenger cylinder) follow your fuel rail to the end there should be a black cap (about double the size of a tire cap) unscrew this and connect a fuel pressure gauge it should be above 3.5 bar at idol and should not drop below 3.2 bar under WOT) Hope this helps
