I know this has been asked and i cant find it. But mine seems that it pulls very hard with quad 215 and hot juice 5/5 i do not have a lift pump yet but it has not cut out yet, anyone running like this with out a lift pump? Also does it hurt to change it alot most of the time i leave the quad on 215 and juice on 0 but if i want to mess around i bump it up 3/5 or 5/5. Thanks for your help

I never ran a lift pump on that setting either.There is a Nitrous 215 that doesn't stack well on 5/5 with the juice and you will experience bursting.

I don't believe a lift pump will add this either

I run the stack with Quad on 215 and I can not move the 145HP Juice higher than 3 without the engine "bucking". Whether it is bursting or having another issue I am not sure.
I added a Lift Pump but that did not solve the bucking problem. I understand you can only force so much fuel through the stock fuel pump and figure I am/was already pretty much at my fuel max before the Lift Pump system I added.
