help with vacuum problems
 

can someone please help me. i got the car running but at idle, i am always reading 12-20 vacuum. when i rev the engine it gets to about 1500 rpm and then sputters and sometimes will die. i am using the vafc hack with 450 cc injectors, and have everything else set up. when i rev it will almost go up to 0 meaning no boost or vaccum on the boost guage. ?????? help please

if you press on the gas the vacuum goes down...

yea as in towards 0 but not to boost. could i have just a vacuum leak?? i think it has to be more than that. maybe something to do with the vafc?

Re:help with vacuum problems
 

It should go to 0 when you press the gas. Then as you drive and the turbo spools you should read boost. If your not reading boost. Check your charge pipes.

mine idles at about that vaccume, it dosent sound like a vac leak that would mean higher idle.

i hate when charge pipes blow off, thats also not good for the turbo.
