Weather or not you can beat the crap out of a brand new motor is debatable. I would break it in personally, but have seen many cases in which 20+ psi evo and eclipses who professionally race..sponsers and what not break the motor in by beating it. I would baby it because its my money and what not. Now beating the crap out of it with a temp tune is just dumb. You have a tune to handle little boost and to stay out of the high revs..whats so hard about that? If i got my car back and was told that the tune was a temp and to take it easy the last thing i would be doing is getting into races. The leaks and what not i dont know...prolly caused by the motor failure...or maybe could have been sealed bad..dont know but it sounds like your son has abused the car on a temp tune...and will prolly blow the new motor up too by turning the boost up with out a tune to compensate or something along those lines.
