That’s not surprising, given how tight the tolerances for things are on the truck.
I don’t think there are current piggy back or ‘chip’ mods that do anything more than add boost, or maybe alter the throttle map like a pedal commander --and-- add boost.
just adding boost is not a recipe for long term success, engine longevity and trouble free service. You may end up with a dashboard light display and truck load of DTC faults for parameters out of range.
my main concern with them is if they are just spinning the turbos harder, you’ll end up with a lot more heat where you don’t need it.
But, let’s hope someone has ‘cracked the code’ so to speak and you’re on to something. Good luck !
