N55 E70 surging/jumping after stage 1+ MHD
Stock 2012 e70 X35i. Just installed the MHD stage 1+ tune and certainly feel the difference. However, when doing a decent pull in a higher gear the boost is jumping around. I’ve attached a graph from their app.
I can hear blowoff after releasing the throttle fwiw. Tested stage 1 and didn’t notice it, but the boost was much lower in that tune. |

Have you changed the plugs? I found some information that recommends running one stage colder plugs for N55 that have had the boost turned up. Just a thought.
