ive been having some problems with my aeromotive fpr, when i push the car the aeromotive fpr works fine at low rpms but when it hits high rpms 4000 through 7000 it drops and that is making my afr curve be crappy. i did 226whp but the afr where at 12.8. i have a safc2 and it's working good it's doing it's job but i think that my fpr is what is doing the problem. when i had stock 550's all around and stock fpr i manage to get 220whp with no problems and 11.1 afr all the way to 7500rpm's, after i installed the aeromotive ive been having issues and haven't been able to get a good tune, anyone knows why my aeromotive fpr is dropping instead of rising???? the fpr is set at 36psi at idle so at wot!! it is supposed to get at 46psi but it never gets there, it just rise and then drops. please someone help me so i can tune the car and have some fun with the car.

thanks
