R81ders I have also been told to upgrade the edge, so I did just that and have not notice any improvements $350 down the drain. I would hold off on the upgrade. If anything I would send your chip to Edge and have them look at for free. The upgrade did nothing for me but everyone’s situations are different. Try turning off backdown for a few mintues to do a 0-60 or 1-4 mile run on level 5. Alot of the problems we are having with the 05 LLy is the EGT's are too high and the edge is defueling. If you go to records on the edge, see how high your backdown % gets too. On level 3 i averaged around 33%-45% backdown. So in otherwords we have to buy mods to lower EGT's to get full power of the edge on level 3. I notice my truck runs best on level one at least responsive boost, and i only see a backdown percentage of 13%. I was told by edge the only two things that will cause the edge to defule is tranny slip % and EGT's. I would do a run with both egt's and slip % on the monitor, i notice my slip % was just fine it was my egt's that was killing me. Im hoping that will all change after my 4" stright pipe
I have done almost everything now. I have cleaned the MAF sensor, changed out my fuel filter, changed oil, trans flush, and purchased a K&N intake (77series). Just paid and had the injectors cleaned professionally. I have also started to purchase diesel from a place I know is very busy. After all this I have notice some power improvements over time.
I ran a 0-60 test again on level 5, disabled back down and turned on tow haul mode. I am now running 0-60 in 7.2 sec.
I just ordered
