I think everyone wants the same. I can tell you this, the factory tune sucks. At 1,200 miles, I drove my 2022 ED over to GDE and had their engine and transmission tune installed. Night and day difference.I'm trying to figure out what route to go for tuning and/or deleting. I just want longer engine life and better power and economy.
There is absolutely nothing wrong with running your ED with the emissions system intact. The GDE calibrations offer, among other improvements, combustion efficiency for reduced soot formation and reduced frequency of regeneration events plus reduced soot loading in the engine oil. I recall reading the GDE solution makes much better use of the low-pressure EGR.
I don't know if the claims for improved MPG are factual since one's driving style plays into that. Last summer, the wife and I took a 3,000 mile trip and we average 32.6 MPG for the entire trip. I also ran Hot Shot's EDT for lubricity for the HPFP.
