After i piped my 90???

[*FoX*KiD*]

ok well i put a full system t-4 on my 90 with a k&n filter

it runs good and everything it jsut has a pretty good sputter in between gears and i was wondering if messing with the air fuel mixture would fix that

if so which way should i turn it?

Did you rejet?

nope everyone said they only make 2 jets for a 90 stock and another one i dont know how big but they said it doesnt make a difference.

it runs fine it just has alil stumble between gears
