Hello from Bulgaria. Recently remapped my Golf 4 1.9 tdi 90hp. I like how it rides but in my logs I see turbo at full trottle from ~1800-2000rpm goes to arround ~2240mBar for ~2 secs. Is it dangerous? How to resolve the problem. File attached Kind regards.

Adjust N75 map and you will sort this out.

Thank you for your answer but this is wastegate turbo and whole N75 is set to 100%. Will it work if I change the 100%,s values? Thank you.

I havent looked at your file, but what is your requested boost? To me just talking in general, the spike doesnt seem so high. Its like 1.2 bar, but this depends on what your stock boost and tuned boost is to sort of relate to
