I was going to ask the same question because trent5.0 doesn't have enough mods to make the engine run lean.

stock regulator is not adjustable and is located on the rear of the right side fuel rail. a good adjustable one is about 100 bucks. get a gauge kit for it as well. one that mounts on the schraeder valve unless you want to run one inside the passenger compartment. the above are correct , also. set your timing back to 10 degrees. '94-'95's are sort of funny when it comes to timing advance. i've tried everything on mine and can't get more than 12 degres before detonation starts and that's WITH premium fuel.
