The only issue I have with my PMAS intake is that the PVC connection to the PMAS tube is kind of wonky. It doesn't sit flush (the silver piece that PMAS has inserted into the plastic tube).
The service tech on the phone said "it's probably the evaporator, it's been happening a lot on the mustangs"
But I don't want the car there for 6 days...I have a call in with another dealership.
Just spoke to the dealer I bought it from. They said I have to drop it off...they'll look at it in 3 days...then they will fix it.
I said, well can I just make an appointment in 3 days? "Nope".
I guess I'm spoiled being our last 4 cars were BMWs?
On Saturday I loaded up my new Lund tune (I think this is unrelated to the AC issue) and I took my car out and turned off my AC system completely.
Today (Monday morning), I got in my car to go to work and I turned on my AC system. It has a weird smell at first and the air started blowing...
Since you are supercharged, it might make a difference. 3" would probably be preferred.
Under 600hp, 2.5"/3" doesn't really matter. Wouldn't be surprised if 2.5" made a little more power.
