New AFPR

[SkURTnDSM92T]

Should the vacuum I am reading change with an aeromotive afpr from what it was when I was running the stock AFPR?

No, it shouldn't. Unless you left a vacuum line unplugged or something of the sort.

What if i had a bad exhaust leak? Like really bad...that would do it right?

I broke one of my turbo bolt, and a lot of exhaust comes out of there...

No an exhaust leak won't cause that either.

It won't cause a vacuum leak, but your turbo will spool much more slowly and you'll lose a ton of performance (this is a byproduct of an exhaust leak before the O2 sensor).

I'd re-check your vacuum lines and make sure that you didn't miss anything during the AFPR install. Look for things like a tear in the brake booster line to the intake since that's a biggie and will really kill vacuum readings. If you can't find anything, run the motor at idle and spray carb and choke cleaner around all of your lines. If the idle changes, you have a leak and need to change the offending line.

Let us know what you find,
