according the mitsubishi, spec is something like 163psi and each cylinder must be within 15psi of eachother or the results are considered bad

 

if I were you, i'd just bite the bullet and make the drive to AMS. I'm in the same boat. whenever I need anything done on my car I had to drive 5 hours to Dallas to see Kevin D...well I moved 150 miles in the opposite direction, so now It's a 7 hour drive, but you know the job is going to get done right.

I just get a list of everything I'm going to need ahead of time, and communicate it with Kevin long before I go, that way when I get there he can just get to work. I'd suggest calling AMS and setting something up for a day or two days when you have time. get on priceline and find a cheap hotel room, and get your car taken care of.
