Im pretty sure the car will be stout.
Ive been running procede for about 1 year in my car. Ive put 14k miles with procede on, beat the crap out of my car everytime i drive it.
I have friend that runs nothing but 100 octane tune on his evo boosting 26 psi, daily driver.
I think if you have the octane to compensate for the tune then you shouldnt have problems with the engine.
The tranny is another thing.
