So after a few months of waiting, I finally had the opportunity to swap out the broken A-413 in the GLH and replace it with the original A-525. Tranny works great, thanks 1FastCSX289, and the car runs amazingly well. Boosts up to 20 psi with no issues and pulls HARD!!! Can't wait to get her out on the track, have a feeling I'll be replacing the 525 with a 555 in the near future!
