its all in your setup and injectors lines and pump combo if it lopes or not. i have a version of the monster pump .093 lines and 6x.018 injectors with a big cam in the truck and mine idles smooth as glass. every once and a while she'll lope but clears out after just a second. to be honest i dont think i would want mine loping like that cause for one its mechanical injectors loping like that beats on the nozzel pretty hard.

thats cool i always wondered what made them do that sounds pretty cool but i would have to agree with bandit have to be kinda rough on things

It's not a gasser, it shouldn't lope like one either. Causes are usually oversized fuel lines, crossover tubes, or failing VP or injectors.

That truck sounds like it's about to die. I've heard lopes but THAT seems to be overdoing it to me! (Just my opinion)
