Good luck, sounds like you could use it!!!!
That is my worst fear. We've breifly discussed that.

You will track the vacuum leak down in no time.
They might. I only dealt with the tuner. And they didn't have time to fool with it. Besides, I had just paid 600.00 to try with a tune.

But, if I end up pulling the maggie and doing all the work and I still have the leak, I'll go have that test done. Maybe I should try it before hand.

Discussed this too. Not sure how to test it. It encased so you can't really visually do it.
