if anyone could help i would appreciate it!!!

i am having a drop in boost while accelerating with full throttle...(usually uphill)
i usually boosty around .9-.94 (reading on my fc) but ive been noticing that sumtimes will only boost around .3-.34 anyone know what this could be??

 

What boost are you tuned for?

It's possible that you are generating enough boost to stick the turbo control solenoid, which will drown out most of your boost above 4500rpm.
