Message ok so after deleting aiv and prvr today and fixing afew leaks... i realize that im spiking 16psi and going down to 12 an holding there. i had someone look at it an told me the controller sucks an making it spike no matter how much you open or close it.

i think i was running so rich cause my timing is off.
1 question for people that dyno cars, my dyno said 15.8 at 288rwhp so would that be my highest boost cause it spiked for a second? it would also explain why the dyno chart starts high and slowly goes down through the rpms.???

for my problem wiht the wastegates when completely open only running 16psi, i dont think when i unplug 2 vacumm lines going to the intake pipes it is open wastegate. i looked at the lines and it t's off near the wastegate. i looked threw the manual online but its too hard to see what it t's off to? everything is so close in the pic. i ran the car with the boost solenoids unplugged an plugged in and the same results no matter what so i left them plugged in. also it doesnt hold 16psi at open wastegate niether , it spikes to it and comes down to 12 again.

hopefully i get to rent a timing light an learn to use it tomarrow.
