Also, The car was not tuned. It was supposed to be babied. Not beat to piss.
We could have put it right on the dyno, tuned it, and given it back to the owner, but it would not be best for the motor.
We have done this enough to know that you want to give the motor enough time to break in, rings to seat, ect, before you throw almost 20 psi at it.
We always, always do 500 miles of easy driving, oil change, then dyno tune.
And I typically trust my customers to put the 500 miles on because #1 I usually don't have the time, and #2 you would expect the customer to care enough about their investment to not beat the crap out of the car and mess things up.
This situation involved a young man who's father bought him the car, and was paying for the entire build. He obviously didn't care of the outcome because he didn't pay for any of the car, or upgrades. He just wanted to get in and Race anything on the road. Even though we told him to drive like a Grandma. He was warned to not get into boost either. He knodded and it seemed like he understood the importance of this, but obviously not the case.
