GDE/SFT? Tune

Hey guys, new to the forum and a new owner of a 2018 ecodiesel thats fully stock.

I have been trying to figure out which tune to purchase and the research has been confusing to say the least. Some people say GDE is the way to go but also say their new EPA compliant tunes are trash. Other people swear by SFT but say they do shady business and their tunes arent reliable. I emailed GDE and asked a few questions and got very "EPA compliant" responses saying their tunes will not work with any EGR deletes (however I have been told that GDE's tune does disable the EGR?) When asked if their tune supports turbo back exhausts or straight pipe exhausts that delete the DPF, I was firmly told that the GDE tune will not work with a turbo back/ straight pipe DPF delete and it is ILLEGAL to do so quoting exact dollar amounts for fines by the EPA if observed. Not sure if GDE is just covering their asses via email and their current tunes do support DPF removed exhausts.

When I emailed SFT I was confidently told that their tunes disable the EGR and that their stage 2 tune requires a "fully deleted closed course exhaust" (not clear as to what this is? It seemed like SFT was very open about their tunes disabling the EGR and being DPF delete friendly.

I say all this to ask for advice and to hear from anyone that has purchased a tune from either GDE or SFT recently. My main goals for my truck are to run cleaner, get better gas mileage, and sound like a diesel should. I dont necessarily want to delete my EGR but definitely want it disabled. I also want to run a turbo back or straight pipe style exhaust (not sure if this is even reasonable).

Sorry for the long post, thank you for the guidance.
