Problems with my tune

Hey guys so I had my c63s tuned by a local tuner and having issues... So at first I installed downpipes and took out ecu to have it flashed, got the computer back and installed. Started up not problems and everything was good for about a week. Then I started having problems with the car going in limp mode after full throttle. But then the car off and on and it's fine again.
Contacted the tuner and he had someone look at it and couldn't find any issues. Send to the dealer and the checked it out found no issues and updated the computer back to stock. So then driving the car everything was fine again with no tune. i drove the car for 3 months everything still ok and decided to tune again. Same guy and after a couple runs it went to limp mode again.
so what I noticed is it only goes into limp mode when pedal is to the floor. And it just cuts all boost to the car. Anyone else having this problem???

I think you've already answered your own unasked question: The tune you're using is not reliable.

Number 1 issue "local tuner"...Why not use someone on here who has a great reputation and has done hundreds of tunes on our platform?

What is this guys qualifications? How many tunes has he done on this platform? Do you know anyone else with this tune?

The simple fact is everything is fine until you load the tune, it is a bad tune and likely...you picked a bad tuner....

I asked my tuner for 1 psi more boost and he said NO you will destroy plugs and are at max safe boost. Willing to bet its your plugs and running to much boost

i think I agree - pull the plugs and narrow the gap to.029 on all. that will tell you if its spark blow out.
