2017 Expedition_First ecoboost tune_some questions
I've been somewhat using Metroplex's guide for this tune. I'm pretty happy with it so far but have a couple questions.
How much of an increase should I be aiming for on this? Stock was around 13.5-14.5lbs of boost, about 37lb/min air mass. This tune is currently 16.5-17.5 lbs and up to 43 lb/min air mass at around 5300 rpm. I wouldn't mind going further but wasn't sure what the stock turbos are capable of.
What should I do with cat overtemp? I increased the temp 150℉ but I'm still occasionally hitting it. I also changed the enrichment to .78. What are safe settings for this with the cats still in place?
I left WOT Lamda at .82 since this is a heavy vehicle and might do a little towing. Is that good or is it safe to lean it out a little?
I've attached stock and tuned files and logs. I would appreciate feedback on what I did wrong, right, or not at all. The stock log was with 85 octane.
