Make sure your wastegate is mounted the correct way, the bottom of the "puck" should be on the pressure side of the exhaust. If you can, take a pic of how its mounted now and post it up.

 

Good move. I wondered why no one puts it there.

Having it t'd off in the crossover is asking for it to overboost IMO.

 

ok guys ill confirm what i did for 15#'s of boost but this will not apply to everyone, I had to order a extra inner spring to go inside the primary spring that comes with the jgs wastegate and i also had to run full reference pressure off the turbo to the bottom side of the wastegate. Hope this helps anyone running into the same problems

 

So is it maxed at 15# or do you have some left?

 

If your asking about the turbo being maxed out that's a negative, I have had it up to 20#'s on accident before...

 

No, I mean can you get the wastegate above 15# now?

 

Yeah i would take the reference line off and run spring pressure, or hook the reference line to the top port and put boost controller in line

 

Little update on this, i ended up putting a 50mm wastegate at the cross over and another on the log manifold before the turbo... Im running a AMS1000 and it gives me total control cause i can bleed off exhaust from both sides of the motor, this is prolly a more extreem way of doing this but it works flawless for me and in most situations you shouldnt need two big a$$ 50mm to do it but i did just because i wanted em to be the same! I can run unreferenced and get 6#'s of boost, i can put 10 psi of co2 behind em and get 10#'s of boost and the same with 15#'s=15psi behind gate.... I havent tried any higher yet but im sure my psi number will be pretty close to the boost number i wanna run... Hope this helps someone in the future
