Upgrading 2018 platinum max

happy holidays too all. I just bought 18 expedition and looking for the best upgrades to enhance performance, fuel efficiency, and towing. I did buy a pedal commander ( love it) makes this baby accelerate a lot quicker. But I know I need a tune to really get her going. But which one??? Air intake single box or double filter?? I plan on replacing exhaust manifolds that are fully bored out, and replacing trans cooler from raptor. ( just seems original is a bit small and fluid gets hot on Highway) all your input will be greatly appreciate. Thanks

Follow up to original post. After laborious hours reading reviews and talking with multiple programmers I went with the SCT X4 programmer with 2 custom tunes for upgrades I’ve done. Boy can I tell you the “BEAST IS ALIVE”! I wish I had extra money lying around to finish her but right now she’s put to shame multiple vehicles who think she’s a cow. Stock 400 hp I think with intake , pedal commander, and SCT X4 programmer I have 500hp (maybe more) saving up for complete catch can system and exhaust system from manifolds all the way back. (Downpipe with cats, bored manifold’s, and 3” muffler) then I’ll throw in 160* thermostat. Definitely a long way away a set of turbos. I was truly hoping readers on here would have given advice. Because these upgrades are expensive when you’re disabled. My last Ford before she’d retired after a collision was a 2000 Excursion 6.8 that was getting 13 miles per gallon without a tune.

How is this tune working out?
