Would like to know which level should i put my quad 215 and my edge hot juice in when stacking them? I heard that theres a level on the Quad for stacking with the Hot juice but only see a level for NOS????????????:help:

Quad level 215 (without nos) and my HJ on Power #3 an LB #5 works great for me. No bursting as long as the truck is completely warmed up. I think the NOS tune just adds more fuel thats not needed without the nos. You will burn enough fuel and blow a big enough soot cloud without it.;)

With my 1 year old Quad 215, I can not move the Edge/Attitude (145hp version) above level 2 without bursting. I would start bursting near 80mph or so.

I have just installed the SD Lift Pump and will have to more testing. Tested some after the install yesterday. Engine was not totally warmed up and experienced a small burst at 90 mph. I let off at that point and went home.
