Hey guys. I have a stage 2 and have recently had the gas cap cel issue. My evap/purge is always disabled on my map tune.....should I enable it? I have heard you can lose boost through the evap system also. Does it help to add a one way valve? Thanks!!

make sure you cap off the lines , and somtimes if you took the fuel cage out to do some fueling stuff theres a slight chance you might not put it in tight

I need my evap to "ready" but i have it shut off in my tune. I have this capped off and am not sure if it would throw a light if i turned evap back on. is this ok to be capped?

Don't you need to keep the line uncapped coming from the tank to the engine bay so that the tank can still vent?

It needs to be connected to a vacuum source to actually pull the excess gases.

Just having it open to air does about the same for it as capping it.
