because the egt modeling would be off, right?? thats what ive found when searching, that once you have downpipe, you can disable BTS, or just raise the BTS EGT threshold to where it wont interfere.
is this incorrect?
so what are the benefits then, besides a slightly quicker spool up? holding more boost longer in RPM range??
I do not think you understand in the slightest what BTS is there for.
It is component protection. It works by adding fuel to cool down the combustion temperature.
You have removed the CAT, but removing BTS and relying only on ATR (if ATR is even active) will result in cracked exhaust manifolds and failed turbos.
I think you should better educate yourself on the function of the internal combustion engine, so that you can make informed decisions and understand what every module is there for.
Even reading Funktionsrahmen about this function tells a great deal as to why it is there.
