Sounds pretty good at home with the sub-woofer.
I can't help but notice the "tinny/mettalic/hollow sounding hum" at 23 seconds in.
Is that the sputter you're talking about?
Or when it actually dies?
Could be a fuel pressure problem.
The grey smoke sounds like a rich condition.

Probably find better answers than I can give, since I'm not up to the technology of the electronic fuel injection age...yet.
Hmmm, AtlasF1 forums. Haven't found those.
I do read the forums at Speednet
