FUEL INJ. 420/ with pipe but no programmer
Hey everyone.. Is it possible to run just a pipe and no programmer on a FI 420..?? I know they run rich out of the crate to begin with.. I live at high elevation so I do need to run it on the lean side.. I also have a uni filter and 1.5" snorkle.. I know someone that said he gets better performance from a 2" snork and just a pipe than what he got from a 1.5" snork, pipe, and programmer??? Is the old spark plug look test the way to go.. If i'm still running rich after the snork and uni, maybe getting a pipe and running it for a bit, then check it...???? i DONT want to run too lean as that might hurt the engine.. But I dont want to waste $ on programer.. I know the pcIII lets you take away fuel, but for the $ i want it to make a large difference.. Not gonna get one if it wont count!!
