P259E check engine light with little to no boost

Are you sure it’s not just stock boost feeling Did you have EWG wires?

Even though it’s a pending code have you tried to clear it? Sorry I forgot emojis don’t work on here.
I did have EWG wires on as well but removed with ib4

I would be willing to bet- if you put JB4 back on. But don’t put EWG wires on. Reset battery and turn bit5 on that your car would be back to normal.
I think I have done that and it did not work
What is bit5?
On the JB4 settings. It’s to make sure to turn off Wastegate control. I have never seen a stinger with that code that didn’t have EWG wires. So why I think as soon as the computer knows they are gone it will work. I could definitely be wrong. But I would bet on it!

I did swap out the ecu and that still did not fix the issue
No idea why it’s not resetting for you. That code is triggered by EWG wires. Once it knows it’s not there it should be working normally.
I will unplug and plug back in to see if that’s works, I don’t think that’s the issue

While you are at it, check the wires, make sure no damage to them or the plugs themselves.
Good luck!

That fixed it!! Thank you much.
Did you ever get it to work I’m having the same problems. All started when I did the EWG wires. I have it at a shop and they can’t figure it at aswell
Do you have an ECU tune/flash?
