Well after researching and pricing both options out, looks like I'm leaning towards the vacuum set. The hydroboost setup with all new parts is going to set me back a little over 320 while the vacuum setup is at 260 not that big of a deal to some but I could use that extra cash to get new stainless braided brake lines. My car is an occasional weekend street car with a few trips to the drag. I don't think I need big boost launches I've been happy with the 4psi launch with my bad powermaster. With that said, the vacuum setup is much simpler to swap. Hope I don't have any regrets.
