So I went to get a tune couple days ago and apparently my MR didn't like to be tuned at 26psi. And it was suggested that I might have a boost/vacuum leak.

I have the Injen UICP and Intake system installed and heard that the couplers from Injen might need to be replaced because they were crap.

Anyone suggestions? I'm planning to take it for a boost/vacuum leak test but don't have time right now. Is it something I should be concerned about if I do have a leak and don't fix it soon? What do you guys think of the dyno graph? Should my curves be different?

 

Always perform a boost leak test before strapping on the dyno. Who tuned this?

 

Doesn't matter who tuned this right now. Don't want to point fingers.

But do the numbers look right? I mean I'm pretty sure I've seen better numbers on the GSR bone stock, but what about the MR?
