;d turbo is a dsm t25, and after doing everything they tell me the internal wastegate wont work, its set at like 12 psi i need like 8...they say with the wastegate and labor itl be like 500 to go external wich is way to ******* much....anyone have any ideas?

 

they make these things called boost controllers

 

its working..... but you want a lower boost? You can use a different internal wastegate. I just bought one, and managed to fit it on my car, it boosted like 10 on my guage, but it was likely more like 8 ish... don't know, you could also set it so its always a little bit open, but thats gonna hurt your spool up. Did you buy the turbo used?? Did someone smash the diaphram to get it to boost up to 12? Why not do 12 psi.....
