ok i was think about this for a while now and want to see if it possable. i just hooked up my meth and trottle boday spacer about a week ago now and i dont have the meth in the lines/tank (reason not tune for it yet). the line ran from the trunk to the trottle body spacer just wondering sinse there is not meth in the line/tank can that be the reason why --my boost gauge is movering at ideal or is it a vaccum leak. please help

 

anything behind the throttle body is gonna have vacuum. if you arent running meth right now put a cap over the npt fitting because yes it will cause a vacuum leak

 

anything is possable wit a trottle boday spacer

 

well it after the trottle body so that the problem u think or is a vaccume leak like a broken gasket

 

i think you may have another problem. the way i had mine set up. the vacuum line that tells the pump when to kick on should be sealed, no leak. and the checkvalve on the methanol line(one going to your tb spacer) should be sealed as well. so you may have a leak somewhere else. check the fitting where your vacuum line for the methanol pump connects with the vacuum line coming out of the intake manifold.

 

i the only thing i have hooked up is the is the meth line i didnt hook up the vaccume line hoes yet, that goes to the control box. i have the check valve in everything on. how do u know i have the aem kit?

 

it doesn't matter what kit you have. generally all of them are going to have a vacuum line, and all will have a methanol line..obviously lol. and no matter how its hooked up or what kit you have..if its done properly the boost/vacuum shouldn't flutter at idle or any rpm.

 

so it a vaccume leak i guess? lol
