Intake Manifold Pressure

[FirebirdGT]

Anyone ever take any data on the intake manifold vacuum on a 95-98? Maybe at the EVAP nipple on the TB?

Mine runs -16 to -18 vac. With the VS cam , dont run it off the TB, I think its off the map sensor. Don't remember the stock cam, maybe -20 to -22 vac.

Are you looking for manual numbers or readings off the map sensor? I probably have some stock logs lying around I can check.

I'm looking to see if anyone ever took a vacuum reading at the EVAP nipple on the side of the TB. [only applies to 95-98]

I use to take it from the TB but found it easier to take it where the map and fpr is and Ive blocked the hole in the tb. You looking for a difference in the 2?

I just want to compare my reading to someone else has taken the EXACTLY same reading. When I'm done with the Mod - I'll tell what I've done. :)
