[QUOTE="VFORCEJOHN, post: 13895879, member: 158331"] I have a 2004 4.6 running a very similar setup with a ZEX wet kit. making 241 motor and 341 NOS. Mine dips rich, but not into the 10's. Ideally I want to see 11.5 range it's about 10.9-11.5 range. I had to lean the fuel out, I run 900-1000 psi bottle pressure. I also use the dyno o2 sensor and screw it into the exhaust. perhaps all you need is a smaller NOS fuel pill? Less NOS fuel pressure? OR make a NOS tune and suck some fuel out of the motor past 4500-6000 range. I'm no major tuner like most of these guys, it's fixable no doubt. I have my own dynojet 248x just so I can mess with things when I want to. John [/QUOTE]
