Well I did finally get out to try it again. I did put the updated BD tune in it. I wasn't to convinced that it would be in any better, but it did run real well. Bogged a couple times, but nothing like it did before. Not enough to effect anything. Snow wasn't quite as deep as I had been riding in but still and honest 2'. Was wondering if it was maybe exhaust blockage with our heavy snow, but it does have a tunnel dump so idk. Was also riding above 5000 ft where I had been riding around 4000. Still running straight av gas.
Trade that hunk of junk in for a stock 165 2.75. Then maybe you will finally be able to make it up as far as me ?

I suspect it's in your tune.
BD should have some fresh tunes.

I've got tune 4.04, which should be available to the public soon.

19 850 / Indy Dan head / stock head had a big with pump or 50/50. Didn’t matter which tune.

Put high boost tune 4.01 in sled rips just fine just can’t be WOT for more than a few minutes or sled retards and have to restart.

Added intercooler..... All business all day long now !
