I know most don't care about the economy and most of the time I don't either. When I take the wife for a 160+mile putz out site seeing it sure is nice not having to worry about not having enough gas to get back.
If you're constantly overshooting load, something else could be up though. You're going after the timing symptom that's there for safety. I would try lowering your wastegate crack pressure, as it may not have been calibrated right from the factory. Not in your case, but I'm also willing to bet for a lot of people this 'surging' is really belt slip though.The pics of the datalog I posted up was a stock tune, it even did it with the cat in place. The dynojet tunes bump there's up to 1905F roughly and it will still hit it easily when the load overshoots the desired load=cruising. It helps bumping the EGT threshold up but that's not the fix all. Getting rid of the rediciulous timing retard fixes the high calcuated egt's.
Yeah it would be nice if someone would support switching tunes on the fly, but that's mostly a feature of piggy backs. Eco mode is nice for the putzing thoughI know most don't care about the economy and most of the time I don't either.

That will do it for sureI suspect I have found the issue with mine. Removed the secondary clutch and discovered one of the roller's split, consequently taking out the helix bushing and movable sheave bushing. I have parts on order so it will be about a week before I can confirm.
