I have a t3 ihi turbo and when I hit the gas fully throttle, it stutters then gradually hesitates to full boost... I have 390's and fields sfc...what do u think it is??? Thanks, Tony

 

sounds like a tuning problem. try a fresh set of plugs, if that doesnt take care of it, hit the dyno

 

I just put 2 step colder plugs in it and I checked them tonight and they are black.. so u think I should lean out my afc??

 

yes but only a bit at a time and watch you a/f's

you car is studdering cause too much fuel

 

too much fuel my cars doing the same thing but i have to tune it on a dyno since i have hondata

 

so the stuttering is definately too much fuel? I will mess with it tomorrow and I will keep u posted on how it goes... thanks guys. what else might if be if it's a freak of nature?!?! lol Thanks, Tony

 

what's your a/f ratio?

 

I have a apexi 3n1 turbo timer.. 10.0 being rich and 20.0 being lean.. at idle it sits at about 12.5-15.5 so it's a little rich.. I am gonna tune it one the wway to work tomorrow...y do u ask about the a/f ratio?

 

ok... I have been watching my af gauge and it pegs lean when full throttle.. the reason for my stuttering is not enough fuel...am I correct??? please correct me and any onther possibilities are always welcome... Thanks, Tony

 

it can stutter from being lean too.
