Tune vs jb4

[Kingreg]

Howdy stinger fam.
Had my brand new 2023 stinger fitted out with k&n intakes, x-force exhaust. Got the ecu tuned and had limp mode issues from day one (nothing major only sometimes) was told ecu needed to learn.
4000ks later still no good. Took it back and they “fixed” the issues. Was fine for about 30ks them constantly over boosting. Was told to only drive it in sports mode.
Got the shits told them to put back to stock tune no issues now. Was the the blow off valves solenoid was the issue so they just tuned around it put new blow off valves on and they will put tune back in.
But debating the JB4 option to have more control over everything then just flashing the tune.

What are your thoughts ? And what is everyone running extra parts wise on jb4 ?

Limp mode from the start is no good. Did you change your plugs too right? Who did the ecu tune? Reputable ecu tune has more control than a piggy back tune 100%.

Just curious about the X-Force exhaust, did you come across any fitment issues on the facelift version of the car?
I have an X-Force V2 with Varex ready to be installed but wasnt sure if this was for the favelift model or pre-facelift.
I asmued it would be the same set up underneath besides the bi-model system so the fitment would be fine but I'm just curious since you've added this to a 2023 model already.
I also run the K&N intakes on mine and couldnt be happier with it.
