When I first installed them the car ran great. However recently (its only been about 3-4k miles) the car seems to idle funny at cold start up and seem a little underpowered compared to before. Can the funny idle also be the vacuum mod that I did to the bypass valve?

Any help would be appreciated!

will the snow kit work with the pump above the tank??

 

Any idle issues that occur after the VGS mod indicate a possible leak somewhere. Go back and make sure all hoses are connected and sealed properly.
