Mine goes at 8-10 at 2500 thento 18psi at 3000 Immediatly drops to 17,then drops back to 15psi at about 4500 and 14/13psi at about 5500.

Wish it held at 18psi the whole way... Not sure if the mine is right. But i beleive yours is right as the ecu protects the car car from unsafe torque levels below 3000rpm.

my car did go to 12-15 with a Manual Boost Controller on at 3000 rpm put that's off now and I think its better for the car put I don't now if the t5 was went to b like that

With a mbc the boost can get to the end of the white on the gauge by about 2500k..
