Need M8 BD RG #'s for 1500 to 4500 feet.

I know each sled is different, but I'm hoping to get BD Race Gas numbers from a couple people so I know what is a better starting point than BD's numbers. BD only lists one set of RG starting numbers on their web site & it has to be different for the 08/09 and the 10/11 sleds. Please include your CR number and Fuel Pressure as well as the elevation you are riding at.

#'s will go into a friend's 2011 sled running new kit with a 2009 head so numbers for a 2010 or 11 would be great, but I'll need numbers for my 2008 m8 RG ADA kit as well. I can tune it eventually, but I'd rather not spend a day tweaking when I could be riding! Thanks! --Matt

These numbers are useless unless you post a fuel presure.

Agreed. Am I correct to assume that you can't adjust fuel pressure on the new kits and they are typically 42-43psi at idle & increase at 1lb fuel pressure per 1 lb of boost like the 2008 kits with external regulator?

not sure on the newer kits but Junior @ BD said stock fuel pressure is where you want to be and on a 2007 M8 its 42LBS.
