USA OM648 power upgrades?
Jerry @ Eurocharged in Texas has been working with me. I have a 2014 ML350. I think we have finally got the tune down pretty well. I have had to send it back 3 times but last time seems to be really good. I am also running a hybrid billet ball bearing GT2363VKLR. Avd Turbo helped me build that.
