Any gains?

Even I'm surprised at this result. The numbers and this video just don't add up! If that video is accurate, yipeee for me I'm a happy camper.

But I guess I will need to try it out for myself.

Raced a C63 last night a few times, from 30 he got the jump (Traction was an issue for me) but once we crossed 70-80 mph the M5 started walking hard. The acceleration from 80-140 is just insane. I'm only running stage 1 tune.

Bear in mind - I had a passenger, two jackstands, a jack, and uninstalled downpipes in the trunk. Maybe an extra 4-500 lbs LOL.

The C63 must have been tuned. A stock m5 should be quicker from all speeds so a stage 1 would eat it.

Those downpipes shouldn't be in the boot, they should be under the bonnet.

They are under the bonnet now and he was tuned and had catback system. I was quicker on all fronts but was having trouble with traction plus weight

I went from an Eurocharged W204 C63 PPP to a stock F10 M5 and my M5 was quicker and better in every way.
Great noise on the C63 though with secondary cats out.
