Had my APS installed at 1500 miles, just broke the car in, then got it installed. Now at 10k.

 

Had TN kit installed at 10k, 10700 now, a month with the kit. lol I'm a youngn'.

 

12,000 miles with APS TT @ 9 psi and 16,000 total miles all of them on stock internals.
Just as an FYI - The install, tune, maintanence, and checking your guages often (A/F, EGT's, and Oil Pressure at the minumum) will give you the miles, otherwise you are just lucky.
