Various comments on various sites regarding boost solenoids and hesitation under high speed/boost
Comment 1
i had this problem 1 day after tinkering with the engine in my 2001 classic. was like hitting a brick wall at about 4000rpm. i sh*t myself! i checked all the boost pipes for leaks when i got home, turned out i had knocked the bottom pipe off the boost solenoid, oopsie! Re-fitted the pipe, prob solved. i would check all the boost pipes.

I don't have any boost problems taking it of the bcs. First thing to check is boost leak. Might worth trying the car without the dv as they can be a problem. A doddy boost solenoid could cause boost issue also and is a cheap remedy.

Fixed it last night. As per Turconator, I replaced both the fuel injector relay and fuel pump relay, checked the cap, rotor, distributor, fixed a few vacuum lines--most notably, the wastegate vacuum line to the boost control solenoid
and the carbon filtration purge valve vacuum line going to the canister. Just for fun I ran some seafoam through the vacuum tree, buttoned the car up and went for a nice drive. No problems, and the car runs like a champ

Accelerating on WOT, any gear, the car pulls then slows as if I've backed off a touch, then pulls, then backs off, etc. Still pulls to redline. No apparent misfire or strange noises. No warning lights.

The boost solenoid is in front of the drivers side strutt under a small cover. Do a quick search on here for hot to clean it, it only takes about 20 mins to do. Its possible you may have some dirt in it and this can cause the problem your experiancing, its the cheapest and easiest option to go for first.
So..........
how do i get to these boost solenoids? what is the easiest way so that santa and i can tackle this? looks like one side will be easier than the other but the passengers side of the engine has idle pipes in the way etc.
apparently these will break when i take them off to get the the boost solenoids.
Is there another way to get to these i.e under the car, etc and if not how can i take off the pipes easily without breaking them?
