Right, so the tunes will lean the motor closer to optimal vs the stock tune, thus giving better hp/trq/mpg, but at the expense of wear. Although I'd imagine under normal driving conditions the motor isn't going to really suffer at all. More likely it would be harder on the engine if you drove it at the limit all the time.
Yeah pretty much. My car has been tuned since 1,000 miles have been on the ODO and I'm at 28,0xx now. The key is that the top tuners know how to utilize the power of the vehicle's PCM and safely alter the stategies to maximize performance without putting the longevity in danger. Any joe blow with access to SCT software can bump the timing and lean it out for more HP and promptly grenade the engine within minutes.
