I am trying to figure out a surge at 3100 rpms. I can really get it to surge dropping down through 3100. Doesn't do it at any other rpm but will do it in just about every gear. Lund says it is a "throttle" issue. I tried switch back to the stock TB (running a vmp ) but it does the same thing.
It has all the upgrades, injectors 79mm pulley PMAS CAI etc. Drives fine otherwise. Not sure where else to look?
