Studdering at 65mph

419 4
Ok i got an 02ho 6speed. 150 injectors, 62mm phatshaft. Edge comp, and a smart set on 6, duration is turned all the way up and no timing set with the smarty. So when I'm going 65mph in 6 gear i get a studder but as soon as i bring the rpm's up it goes away. I already replaced the tps with the timbo app. Am i just running to low of an rpm or something else wrong? Thanks for the help guys.

You might try shutting off the Comp or Smarty one at a time to see if one of them might be the problem.
