i have a 00 180q...ran into my first problem so far....only have intake and a forge 004...on the hwy in 5th gear i floored it...and it spiked to 15psi and cut off and dropped down to 3-5psi.....then during boost i could hear my turbo squeel...got home put back on my 007 it stopped the squeel but boost is still cutting off @ WOT

 

test drove the car a second time....boost holds better now...but still spiking to 15 and dropping to about normal (9-10psi) i've never had this happened before....in a couple more weeks i'll be getting it chipped and fmic pipes mounted on.

 

Doesn't sound that bad. I am spiking around 26 and holding at 21. That is on a Revo Tuned 225

 

Not seeing a problem here. Sounds like just changes in load and gearing.
