Cool... which trim / engine did you install on?
Any dyno results or seat of the pants feedback on the difference from stock?

2021 Lariat super crew with the 3.5 EcoBoost. I don’t have Dino test but I can definitely tell a huge difference for sure!!!! Really really big difference! Jay before should have dino results for the new 2021 eco-boost soon because it comes stock with 400 hp vs The 2018 that has 350 or 60 hp.
No buyers are remorse whatsoever!!

Which tune are you running? 91 octane? 93?
I had a JB4 on my VW for a while before I had it tuned and I was pretty happy with the reliability of it. It only provided about half the gains that a true tune could provide though.

What kind of hit did you see on fuel efficiency?

Love to hear how it's working out so far. Also, is this less likely to show in a potential warranty claim if removed vs a full on dyno/ecu tune?

Any update ? I haven’t decided if I’m doing JB4 or a custom tune?

JB4 isn’t a can tune- it’s a override without a flash - no flash- my dealer doesn’t care (we’re best friends). That’s the benefit .
i come From the car world so I agree with you on custom tune - except I want to be able to
Flash it back. Also Livernois has been back ordered and they are located in Michigan- not necessarily convenient if you have issues with your remote tune - it’s hard enough to get tuners to take care of you when you’re local let alone being 2500 miles away .
