Well if it was me, I wouldn't be spraying 100 shot dry. I'm not saying it can't be done, but it's not the greatest way of doing it. While you're at it, ditch those Zex plugs for some NGK coppers, 2 heat ranges colder than stock. Zex plugs are terrible, I had them. I'm thinking bigger injectors than stock would help out to flow more fuel, you might want to talk to Zex and see what kind of fuel pressure you have when spraying 100 shot on their kit. Let us know how it goes!
