Hey Richard, reviving this thread. I have been driving the car since the last post on wastegate boost, which is around 7-8 lbs. Car drives just fine and has decent power. I'm thinking about bringing the meth back on but Jason (AMD tuner) thinks we may have minor piston damage which could be our culprit for the meth system not working properly. Like I said the car runs fine on wg boost, doesn't use oil, and pulls strong. On meth it's supposed to be running 24lbs taper back. I intend to do pressure test and leak down test in the next coming weeks to verify if there is any piston damage. Just curious do you think piston damage could be the culprit? I just don't understand why it runs fine on wg boost but not on the meth system.

Thanks for any input.
