HPM doesn't tune cars, frankly I wouldn't have them work on my car, thier quality has really went down hill since the new owners and the move to the new location.
Dan @ Dynosport does a good job, thier is also EJ's Dynoshop out off of 132nd behind Skateland, he does a good job as well.
I have a tune from RWTD (Running With The Devil) in mine with no problems.
