I have about 400 miles on my eninge now...boosted
Still going strong...running pig rich though and the mileage is still good....waiting for my chip to arrive, I'm currently using a FTB hack

I figure I have put about 10000 miles running 9 psi on my d16z6 now. I blew a headgasket, but you've got to figure that's your weak link when you've got 140.000+ miles.

But yeah, proper fuel management will keep your motor running right.
