The car pulls harder than before and I can tell that right away. I've had BM3 since the first OTC map was available and this 5.7 is a rocket.
I don't know much about data logging and what not, but I assume Halim@HCP has tested everything and made sure all is safe? My AWRON gauge picked up a max exhaust temp of 1300 degrees C. Which kinda surprised me considering I wasn't even driving that hard, then again Halim pointed out a while ago that exhaust temp reading from the AWRON gauge may not be accurate.
The power is there, the muffled exhaust sound just sounded awkward and I hope it's not something we should be worried about. Will hit the track on Monday and see how it goes under warmer weather and more extreme conditions. I too prefer consistency over max gain.

Omg I thought I was just hearing things but seeing someone else type this out makes me think it wasn't just in my head. I also went from 5.5 directly to 5.7 (had a short stint with 5.6 but went back to 5.5 immediately cuz of burbles)
I can't be sure but i also thought the exhaust note sounded quieter and muffled but figured it could've been my sport cat taking a hit from a bit too much burble. Going catless soon though so we will see.
Still not 100% sure but reading your comment got me thinking again
