Bumping this thread to inquire about compression on higher mileage engines.
I have a 2009 with 112K miles on it, that's been tuned for about 50K. Just got a compression test and all cylinders were at 150, give or take a couple psi. I don't know if this was done hot or cold, and was just done at my local shop vs. a dealership. A bit worried about those numbers given what I've just read even though they're consistent and the car seemingly runs and drives just fine. The shop (which has a lot of experience building their own and working on tuned cars) didn't sound at all concerned over the phone either. Is this engine on its way out or am I worrying about nothing?
