Car hesitating when wet kit hits????
i run way rich on my wet kit due to the high psi of the kit pulling fuel from the rail. you need to check your AFR and see where you are at it could be hesitating because you are way rich.

just got mine off the dyno last week and its going super lean when it hits. fuel is heavier than nitrous so it takes longer to get to the chambers. this will happen everytime you activate. the shift in gears stays good cause there is still fuel in the manifold even after the nitrous stops flowing cause its heavier.
for this exact reason im now switching to a dry kit, since it can be tuned as a low octane setting. the a/f ratio was jumping to 14.3:1 which is extreme. however once the fuel catches up the a/f ratio was 11.3:1 the rest of the way which was great. i want to save my motor so im going dry with a tune.
one more thing i found out fyi is if your bottle is mounted straight up in the spare tire well, make sure the label and valve *** are facing the front of the car, otherwise youll uncover the siphon tube and loose tons of power in third/forth gears. (you'll never know it on the dyno cause the car isnt moving!) haha!!! hope this helps you out.
