OK, so i called the vendor and he will take the HKS wga back since it didnt bolt up. I dont want to hassle with a custom bracket when im not even sure the WGA is the reason for my boost spike and not holding boost till redline. I figured out how to fix my stock WGA, turns out there was a loose stud inside the tip. So im gonna try to adjust it (tighten it) and see how much itll hold w/o spiking past 19psi. If this DOES NOT WORK i have a couple of options:

1. Ditch the cheap MBC for a good EBC and hopefully that fixes the problem...i cringe thinking about spending $300-$450 on a damn boost controller so hope its worth it. Ive never had this problem w/ a MBC on my Honda but then again i had an external 38mm tial WG.

2. Buy a 38mm Tail and run an external WG either off the stock manifold or out of the WG hole on the turbo....and keep the cheap MBC. This will probably be around $300.

3. Buy a good EBC and hopefully that fixes it, but if it doesnt then buy the external WG and have a damn nice setup consisting of EBC and Tial 38mm. Bad side: $750 . Oh and if i do this and boost issues persist i will crash this car into a brick wall.

Advice?
