boost falling at high rpm?
hey! i've got an 88 tII and im having problems w/ keeping boost at high rpms on full throttle. it will hold boost if im heavy on the throttle, but not full. is it possible that it has somthing to do w/ feul. oh yeah im running a t04 w/ 750cc secondaries, and a stock feul pump. help me please?
thanks for the help
ps: i dont believe is my profec b-spec II boost cont.
i've messed w/ it enough to rule it out.

When you say you have a To4 , what is that ? A hybrid or a full out T04E , To4B ?.
If you have a hybrid, those are the symptons. You get 12-15 psi and around 5500 rpm it goes down to about 6- 7 psi.
The way around this is that you need to clip the rear wheel. You loose some spool time, but you can hold higher boost for longer.
