Whipple is ZERO help after the sale. I love their product...hate their tech support.

Pull the intake tube off the throttle body and see where the throttle blade is sitting with the KEY OFF, then have someone cycle the KEY ON while you are watching the TB and see what happens.

If the TB is behaving normally, then yes, you probably have a huge vacuum leak.

If the TB is acting weird, then Whipple may have jumbled something in the tune.
