The Bullseye Power Drop-in LB7 BatMoWheel for your 2001-2004 GM 6.6L Duramax is a replacement compressor wheel for your stock turbocharger. Its unique design increases spool-up, throttle response and also increases power and efficiency.
I dropped this in my 03 dmax about 4 months ago. It has not helped at all with egt's and we did have to pull the turbo to get it in. It is alot easier that way than trying to do it while still in the truck. Other than that I really love this wheel. My mileage went from 16-18 to a solid 19-20. It lights like crazy when it hits and sounds way awesome. I like the wheel, but I do not know if it was worth putting it in. HP wise I have no idea on what it does, but it sure does move when it raps. So it kind of a mixed feeling. Since I have it i do like it, but I don't think I would do it again if I got another truck.
This product works as advertised

I installed the batmowheel on my lifted with 35 inch tires 2003 duramax with california emissions and for me it made an enormous difference. My truck spools up way faster, pulls hills easier, lowered my EGT's, cools down lots quicker, and does better on fuel. It was a royal pain to get my turbo apart to install it but it was well worth it. I highly recommend upgrading the down pipe and air horn while you are doing this mod, because you are already there and its some work to get to that point. I upgraded my air horn and down pipe at the same time I installed the batmowheel so not all of the credit can go to the batmoweel, but altogether it made a really big difference in my truck. The only thing that I do not like about the batmowheel is that if you are pulling boost you will hear the turbo whistling, but hey some of you guys are into that.
Lot of bang for the buck

This wheel works awesome it spools like a mad man but that being said IT IS NOT WORTH THE EFFORT. You have to pull the turbo no matter what. If you have the turbo off you might as well spend the money on intake horn and downpipe.
