Why not open the airbox a little at the bottom. This will give you more air flow thus leaning the mixture. If you open the intake area you are still able to utilize the stock air filter.

I also don't believe they are rich. Lean on top...and going into the ECU to lean them out doesn't allow you to lean out only one part of the fuel curve...what you add or subtract does the same thing throughout the fuel curve.

If you have a bog off the line, it's lean, not rich.

It would be nice for Powercommander to make unit for out sleds....

Not sure if its true but when I talked to Bender about their exhaust, the tech that I was talking with said that the Apex's are running rich from the factory. Bender has Turbo kits for the Apex's so I’m sure from their work on the Dyno they would probably know. As far as bogging out of the hole if that’s your reason for leaning the mixture, that could be the belt not riding high enough in the secondary. You might have to add the washer to the back side of the secondary.

mrance111 makes a good point...basically the same point I make...and that is, without a dyno, there is no point in +/- fuel on an Apex.
mrance thinks Bender has found the Apex rich, whereas Supertuner finds it lean on top.
