i just got everything hooked up with a 3" maf and a 2.01 maft. i have double checked all the connections and tightened all the couplers. everything is zeroed out. i went out for a drive everything is perfect. theo nly thing is after 500 mhz or anythig about 0 boost the car start to sputter, It feels like either no air is going into the engine or i am knocking like a mofo. i have a pocket logger so i know im not knocking, any help would be appreciated thanks

Too rich will stutter terrible ,even one click too rich.If you have the base close then lower the wot down.You should see some knock and then try to go up to have slight knock .I have a problem with mine in that if I lean it then no stutter but have fair amount of knock and if richen then no knock but have bad stutter.My solution seems to be lowering boost,which is what you expect to have to do on 91 octane with stock sidemount and 50 trim.
Your ltrims,mid and high can all be in range yet you will stilll get the rich stutter if your wot is set too rich and rich is right on the wot and mid and idle dials.Injector dials are different..set it to bigger injectors is making it leaner not richer.
 
hmmm you know how the tranaltor has the knobs setup? the aux is on the left then theres 4 on the bottom to the right of the 4 dip switches. is the first knob idle or mid i wasn
t sure. after 500 hz is wot right? so lean out the wot knob?>
