It's not RPM based. It will not go over 130 no matter what I do. Which that's fine as I can manipulate the tables to where 130 is full fuel. I haven't had any problems with fueling at all. The problem I'm having is timing does not match the maps. I had changed some axises around right before this started happening and I'm going to try make a pass with the old axises. It still didn't make sense on the 2 passes tho. Unfortunately I dropped a valve seat so won't be able to test again until October 11th and it's my last run of the year.
