What's the popping in this video, is it too lean from lack of back pressure?
And too lil back pressure is a myth..
Possibly on these EFI systems, I don't know.
But on a motor cycle, carb or EFI, if you open the air ways,
you have to give it gas. And it is apparent when rolling off the throttle and popping. Like these things.
It may be normal but why is it occurring?
I've also read, the cat's don't provide much back pressure.
I've heard straight 6's at the drag strip that sound great,
why is the V6 different?
