I mean if you don't mind uninstalling/reinstalling everytime you have to get service, I'd say go for it. You'll be under the hood anyhow to remove the JB4, so removing the DCI won't be that much more of a hassle.
Wow definitely surprising even though the Cobb car has a fmic. Looks like I might consider switching although i'm nowhere near PTF but i guess i could do an e-tune. I'm prob dynoing my current setup this spring or whenever E85 returns back to normal then i'll consider switching and dynoing that setup to see what happens. Up until now i've always though only reason to go with COBB is if you want easier install
