Might work well. Theory is correct, now if it works.

seems sketchy to me....but who knows!

Ya, sketchy enough that I dont know if I dare chance it. I was hopeing someone else has tried them. They do have a very good feedback rating though.....

Ive seen them brought up on here and other boards before and everyone said it didnt make any difference.

From my experience in tuning cars/trucks those things are worthless. The only way you can ever really do good is actually re-programing a engines computer, and those things don't do that.

Only difference these things make is in the bank account of the seller.

Personally, I wouldn't try it. 99% of aftermarket "speed up devices" don't work as planned. Save your $ and buy a speed impeller instead.
