Meh, i like my forge I've personally never had an issue. I've herd good things on the Synapse bov as well, but never tried one so no comment on that.

 

I slapped it on and that was the end of it. Haven't touched it since...

I, of course, got a 2.5'' UICP to go with it rather than reflanging the stock pipe.

What mods do you have done? I have full bolt-ons (no cams, clutch, or internals) and I'm using the -11psi spring. If you have a boost gauge, you need to determine how much vacuum you're pulling at idle and then you buy the spring for it depending on that. I'll see if I can find the chart for it.

EDIT: Here's the chart...

My boost gauge read -20 in/Hg at idle so I used the -11psi spring and, like I said, not a single problem.
