Well, I guess I can now say that I know what all the fuss is about, after some brief testing anyway.
It's cold, greasy and not great for testing anything out but it shifts VERY well. I've always praised this engine for the fact that it revs so happily and keeps on producing power right to the top of the rev counter (especially in comparison to my turbocharged cars) but this surpasses itself and makes the standard map seem like the engine was being totally strangled.
In a way, 5k revs+ reminds me of turbocharged power delivery as it really likes to just nail you in the back with a power surge and at which point you had better be paying attention. That's as far as I got, just a few 2nd-3rd gear sprints down our genuine private stretch of road (no joke, it's un-adopted).
Other things to note...
- Cold start is louder and deeper.
- Normal driving/cruising has the V8 rumble louder and deeper from the exhaust; very muscle car-like. Overall, it just sounds much much more beefy, if you like.
- Static revving again is louder and deeper at low revs but the AMG bark and snap is still there up top; again louder and but also snappier.
- Crackles and snaps when gear changing or over run, lots more of those and loud.
- Throttle blip? I figured the standard blip was loud but this is something else. I've never seen a town centre of heads snap round so quickly at my car when I've rolled from second to first gear approaching a red traffic light.
Downshift blips also tend to be accompanied by loud snaps from the exhaust when you're driving more aggressively.
I've tuned a few cars now in this manner, at home and I can say that this is no different. The first time that I ever did this my heart was racing in case it all went bad but I'm used to it now so sit back and do as the device says (use the .PDF guide that is supplied on your USB stick to help). You will hear pumps humming, the fans come on and see a series of dashboard lights but follow the instructions and you'll be ok.
