I tried searching for my answer to my question on the site I did not find it. I'm putting a zex wet sytem in my tib and I want to use the 75hp shot. I have a gst fuel pump ,but I here I might need fuel pressure regulator. Do I really need one since I'm using a wet kit and not a dry kit were you have to bump up fuel pressure? I had a zex wet kit on my suzuki aerio and I did not have to change out the fuel pump at all at 75hp shot. I do know about the colder plugs which I'm going to put in. thanks for your info.

i sprayed a 75 shot of the same kit you have, (zex) with out a fuel pump upgrade
but of course i wasnt sparying all the time, and i had msd dis 2 to retard timing on top of colder plugs.
