I've since replaced stock with an aftermarket clutch but never turned off the limiter. I've since deleted EGR which completely eliminated the hazing that was occurring. All i've messed with since are DTCs. The last few days I've decided to turn off the F1179 and see how it does with my next trip but even with it off something is still limiting. The only time I've ever seen a load number over 106% was that first time years ago but immediately enabled it again. I've turned up limit tables to ungodly high numbers, I've messed with base fuel and throttle base tables ton one thing at a time to try to identify whats my limiting factor but I cannot for the life of me determine whets going on. I've even reflashed factory and started again to no avail.
If anyone would like to take a look but. Everything is behaving as if the EFIlive isn't doing anything in the ECM except disabling DTCs. I disabled post injection pulses and I can see those turned off so I know SOMETHING is happening, other than that I can see no changes in data from one to another regarding maximum fueling/torque.
Any insight or advice by the experts will be greatly appreciated. I've been methodical in trying to narrow down what I can but I'm at a loss at this point.
