those injectors will give you the worse idle.

I am up for any suggestions, it is a sand car, so it does not need great manners, but would like the best injector for
WOT,

the car is driven like a road race car, on and off the throttle,


bump for a base Tune, anyone?

0411 can do speed density native, no custom OS needed. you're not going to find a good maf cal in 0411 format for the cartridge maf so just ditch it and do SD from the start. search how to put 0411 into SD mode and then just work in the ve table.

also, any further posts belong in the gen 3 forum since the 0411 is gen 3.
