Now that we have some colder nights I've had a chance to step on the gas and let it rip, mainly on the highway. 60 to 100 feels great
I've been impressed with the MHD tune along with my BMS intake and m performance exhaust.

No logs yet but I know it's a must..

Cheers.

Please do log...My car felt great too but I am constantly getting timing pulls on my MHD stage 1 tune and despite replacing my sparkplugs twice it has not shown any sign of improvement.

Currently running a MHD stage 1 91 octane tune with 93 octane fuel and still getting timing pulls.

You will get timing pulls if IAT is high also. And that stock FMIC is junk. I used to hit 140-180 IAT in summer. Car starts pulling timing when IAT gets over a certain temperature. I think 110 IAT.... but don't quote me.

Does it really? Max temp I have seen during a pull was 14x°F. But majority of my runs are in the mornings when ambient is in the 60s.

With the Wagner FMIC my IAT actually goes down through a WOT Pull.
On the stock FMIC i would hit IAT 180 F sometimes if car sat idling a little.

It is ridiculous that BMW uses such a small intercooler on such a big car. I wonder if the F10 535i pulls any timing on stock tune once the intercooler gets heatsoaked.
