I need your help everyone. My buddy has a 2017 xrs and is running the Pwrtune e85 tune. He’s getting the P0234 overboost fault code and goes into limp modea random times. When the problem happens, it’s during hard acceleration and when duning. We‘ve swapped every imaginable parts from my x3 and it’s still there. The clutching is stock and maybe the issues? Also, this may sound like a dumb question but what the starting rod length for the watergate rod? i understand its supped to be at 10 psi crack pressure but where should we start? With the turbo arm closed and then install the rod? I’m thinking we have the waste gate rod adjusted incorrectly. Don’t know but we’re getting frustrated!
