MAP sensor vacuum source questions....
Posted: Sat May 23, 2009 11:21 am
Hey all! I've got an interesting setup which currently runs fairly well, yet still dialing it in.
It's a 250 Chevy straight six, with 3 throttle bodies, individually feeding the 3 siamesed cylinders. I've got 3/8 fuel line between each t-body to try to make a more even vacuum reading to the MAP sensor. MAP is slightly jumpy at idle, around 55-60 or so.
The PCV also pulls off this source, as it's my only vacuum source available. So does the regulator.
On top of all this, I'm looking at adding power brakes, which might help or hinder the vac signal.
Any ideas to this? Am I ok, or needing to change things? Thanks in advance!
