Being that it's my daily I'm kinda hesitant to tune because I don't want to blow anything if it's producing too much power..trans,driver train,etc. Is there any other mods that would have to be done in so this doesn't happen?

If you are doing the DP, you might as well do Stage 2. It's 10x better for power (ok slight exaggeration) but the DP is what allows a Stage 2 tune. Otherwise just do stage 1, and keep the OEM DP.

this was mine logged only with xhp , stock engine map with cat and opf

I'm in a hot climate, sub-tropical, so boost will be higher than for cold climate to achieve target torque. That was the peak manifold boost that was logged many times for my car stock.

later we will have ambient temps 30 to 35 degrees C , i'll relog the stock map at that time . maybe you have a log of yours ?

Logs of my car when stock were limited as I only had Torque Pro and only a few channels logged but this was typical https://f30.bimmerpost.com/forums/sh...&postcount=106
