BMW M5 F10 Tuners

[Has_944]

Hi everyone, my first post on here.

Little background, I currently own a 2014 BMW F10 M5 in Alpine White, car is pretty much standard apart from Rear Box and Muffler Delete.

Now that the dreary winter is behind us (hopefully), I'm looking to remap my car before VMAX200 in September. Was a little annoying last time I went and the car limited to 167! Currently looking at a few UK based tuners and now that the cars ECU's can be flashed, some American Based tuners. Please let me know if anyone has had any experience with the below:
[*]MSL[*]Evolve[*]DMS[*]DME tuning[*]RK Tunes

Also anyone running software on their car, have you noticed any major traction difference, the main issue with UK is that its never dry and I'm a little nervous a remap would potentially make the closer slower under 100 due to the lack of putting power down. Currently I run the car a gear above and let it through the revs whist gradually increasing throttle, seems to do the trick come rain or shine.

Thanks guys.
Hassan

Mapping in uk you NEED MPS4s tyres. I had MPSS 295, in dry they were not bad in wet again pretty good but the 305 MPS4s are night and day better. I have also reduced my rear camber to -1.0 again makes a difference. I live up north so CUP2 are not an option for me as its to wet

Couldn't agree more. I previously had 295 PSS, but I've recently changed to 305 Dunlop SP Sport Maxx Race and they put the power down better than the PSS once warm. Like any Tyre for these cars - they're dangerous cold.

I've heard a few people reduced the camber on the newer M3's and M4's for better straight line traction, although I heard it affected cornering. What gains did you receive on your M5 if you don't mind me asking?

Wet conditions

You can definitely feel the difference in terms of increased grip. As for impact on handling I cant tell you yet. Not had a decent day to try it out. I suspect it will have a negative effect on cornering but to what degree I don't know yet.

Awesome stuff, this will definitely be something I'll look into. Unfortunately living in the UK we have S*** weather and even s****** road surfaces, which worsens chances of the car hooking up. I've had traction light blinking at silly speeds purely because of the road surface in damp conditions.

I know some Americans on social media running silly power from these S63 engines, but having much more ideal conditions for it. One of which running 1030WHP!!!

If you are having some traction issues in the current weather conditions, a tune will make it worse. Its hard to transition smoothly to full boost on any street tires in such a small rpm range. A stage 2 alone can net you at least 100+ wtq.

Since you still have cats, stage 1, and I'll recommend Mission Performance. But, my first choice is always a local tuner if possible.

Halim and ProTuningFreaks. Or Evolve

They are in this forum.

I have an ess tune

Its drivable easilt in the wet however i find that the dcs doesnt catch as easily as its not used to such a substantial power increase
