No I haven't. Still stock bore with "ultimate tbi mods"Did you have your TB bored out to 46mm too?
I have remove the factory regulator and have an aftermarket adjustable regulator mounted on the firewall. I've played around with different pressures and this seems to be where it is happiest with the current tune.An 18LB spring for your set up isn't enough, closer to a 28 LB spring from a 94 - 95 7.4L would be better.
YesAre you still running the 1227747 ECM?
Supposedly the guy I ordered a tune from did. Not totally convinced much was change based on how it runs. Plugs seem to indicate on the verge of lean at idle/part throttle and pig rich at WOT. Truck will also all but die if you wack the throttle open but doesn't hiccup if you roll into it.Have you adjusted your timing tables at all?
