+1 to the above: If it's been well maintained, the motor should be fine. Stay off the rev limiter and don't forget to disable the traction control every start, don't beat on it till it's warm and if you don't use the KB tune then don't tweak the custom tune for max power - prioritize for a safe, conservative AFR as KB does and you'll be fine.

At 97K you may have other concerns: the condition of an automatic trans at that age or a clutch in a manual car may warrant some budgetary "just in case" thought...
 
That's pretty much the magic question---what if something went wrong? Would you be able to swing it or would it put you in a major strain since the car seems to be a daily driver.
