Hey guys I am new here, I have a 99 Cummins I built as my shop truck for truck pulling, i swapped a 6.7 out of a 2015 into it, still running a vp, it has a monster Mike stage 2.5 pump, his 6x13s cross overs, his trans with bolt together converter, trucks ran decent most of this year in workstock but my biggest issue I’ve had was figuring out what tuning platform I should use. I’ve ran edge/smarty and it ran like total crap, edge on 3x3 alone has ran the best. For next season I will be running 6x18 top feeds in it, the 6x13s were what I could get at the time. Does anyone have any recommendations? I’m sure some of the old school vp guys might have an idea.
