I installed the tial qrj in my car but I hit 30-32psi when i shift at redline. the spring is the 1.5psi. any ideas? The stock one will never go over 28psi

 

Stock BOV was leaking. The Tial is not. Likely need to have the car retuned since you fixed a boost leak...

 

Shouldn't be. I got the car tuned with 2000 miles on it

 

Stock BOV's start leaking around 26-28psi. I just about guarantee you yours was leaking. The tuner had to increase WGDC to make the boost he wanted. Now, you installed a Tial, and it's not leaking, and your car is overboosting.

 

let'sgetthisdone is 100% correct.

 

Interesting. It sucks that I have to put this pov into the parts bin because my tuner wants 400 for a retune..

 

I'll chime in and say letsgetthisdone is also correct. I had my X tuned at 30psi and I can assure my stock DV was leaking. I threw a Tial QR on with a 6psi spring and I did a 75% throttle pull and my boost spiked to 33psi. You need a retune

 

wait a few months, get some more mods and install the qrj then. at least the $400 will be worth it at that point

 

Maybe try checking your 3 port vac lines as well. Mine werent hooked up right and caused over boosting

 

Doubtful. 99% sure the issue is he has a dv/bov that actually holds boost now and does need a ton of wastegate duty cycle to make it work
