There's not too many of us up here with the KB (and I've only done a few thousand kms on mine), but we have a very capable tuner at Steeda.ca (Paul Meister is his name). Paul's been corresponding with Lideo for a few years now, and he's been trained by SCT with their latest software.
As I understand, the KB tune is pretty safe (ie: rich), so as long as you don't drive her way past redline on every shift, you motor should hold up just fine.
A blower won't kill your motor...a lean condition under WOT will, as will constantly shifting her past 6000.
Peace of mind is everything, so I'd reccomend that you find a capable/responsible tuner/installer in NC. Every car is different, so having a tuner near by will save you time and frustration trying to mail chips back and forth to resolve an issue.
A responsible tuner will tell you that safety is the priority, and your car should leave the shop with the A/F at totally safe levels, regardless of the hp#.
Bottom line...dyno the car with a capable SCT tuner...run her with the KB tune...if everything looks safe...you're good. If there's room for a little tweaking, the tuner should take care of it.
