Engine/Transmission (1998.5 - 2002) Weird Boost problem

[Stixx]

Just in the last week I've been only able to hit 26-27 lbs of boost on 5x5, When I could hit 34lbs before. I've change filters, check fuel psi and all are ok. The funny thing is when I hit WOT in 4th or 5th it hits 26lbs and drops off to about 22 then back up to 26. The fade off hits at about 2200-2400 rpm.



With the Edge box off my boost will hit 22lbs and its steady like it should be, with no drop off.



My Throttle postion sensor is going out could this be causing it?



Or is this a Fueling Box causing it to do this?

ok how do you have your wastegate blocked, and have you checked all your intercooler hoses. Also check by the fenders and make sure that it did not rub a hole in the hose.

My wastegate is block via the necked down elbow that came with my Edge Box. It has no adjustment screw it just has a smaller hole.
