I currently have downpipes, full exhaust , intake system, Amr stage 2 tune, im trying to increase the boost, with the scg1 i currently see 15.5psi peak so far, i heard from many people that 26.1 psi is factory?? im thinking thats not true since i can read less, i have the electronic boost valve with coming from original vacuum source that was b4 coming to original boost solenoid, to boost controller, and other end going to both wastegates, i also just got the wagner intercooler uprgrade and will be doing a water meth injection conversion by next week, i will play around some more with the SCG1 and see if i can get around 20 to 25psi ,
