I've thought of doing this for a few years but it never made sense why it would give me more power if I'm already smoking black........I can perdy much floor it at any rpm and belch soot everywhere .
It'd be neat to hear some before and after results of a 3rd or 4th gear WOT accel from 35mph to 55mph onflat ground or something like that. I think the A1 Bentley lists acceptable numbers, my trans isn't stock so I haven'tcompared mine (also I'm afraid how far off it might be).
Maybe it's something more complex?
