okay so i got these nozzles stage 5 and there pop tested to cummins spec... and it has a lope every once in a while at idle i made sure they were pop tested but could it be anything else?

 

my brothers truck does the same thing, someone on here said to check the crossover tubes to make sure there seated good

 

okay ill look at that it just bugs me when its loping makes the truck sound like a POS

 

Hows your fuel pressure?

 

idle 20PSI and WOT 13PSI

 

I heard that some large injectors or cross over tubes can and will cause a lopey idle...

 

okay thanks i was just wonderin maybe a bigger turbo might make it smooth out?

 

my truck does the same thing,i got 150 hp nozzles and after its has been run and i let it idle it will start loping. about a week ago i changed my air filter and it didnt do it for two days and then it started doing it again

 

So you guys are saying when i put my 150 sticks in , i should expect it to lope???

 

IDK if you should expect it but i might bo it...
