: I've noticed lately that when i use my NOS that in 1, 2, and 3rd gears it really seems to almost have a hestitaion or lag effect in the mid to upper range -- keep in mind i'm aware not to go WOT under 3k RPMs - but i seem to get a very noticable stutter or hesitation. : Now whats interesting is that in 4th gear she fly's fast as hell and extremly smoothly -- no hesitation at all - i'm curious why this happens in 1, 2, 3, but not 4th. : I'm running 60 shot wet kit, dual jwt/mafs, afc, 555's, and HKS iridium #7 plugs -- i'm curious for those that have this same type of set up w/ dual mafs what ur AFC is programmed at - i just seem to be running WAY rich. : Thanks in advance,

they only tune in 4th gear. FWIW, when I dyno/tune my AFC, I'll tune for 40mph constant roll...3rd, 4th and 5th WOT runs.
That way, I get a good burn while cruising, and a good burn while racing the elderly. Remember, you have a low throttle and a high throttle setting...you may need to up your TPS % number for WOT.
But I'd recommend tuning the AFC again on the dyno, ignoring the HP numbers...just watch the AF.
Then, make a final 4th gear run to ensure you didn't take too much away from your 'bottom line'
