Had one, didn't like it that much. IMO it didn't add that much to performance. It also stalled the engine if I went from mid/high-RPMs to idle quickly, like when I coast from a highway off-ramp to a stoplight. Tried rotating the MAF to no avail.
There was this whistle below 3k RPMs. Might have been cool if it whistled above 3k RPMs, as you could pass it off as a turbo (heh), but not the other way around.
