09 BD PG M8 A Little Boggy in the Middle and Horible on Gas

[seth25]

I'm running an 09 BD PG M8. Riding at 10,000 feet altitude. 1-2 gals on 112 with the rest 91. Saturday I was running 8.9 lbs boost with 88 duty cycle. It is a little boggy in the mid range. Around 4-5k rpm. My fuel pressure numbers are 17 36 50. My other numbers are all set at zero. I have no ADA and no EBC.

Should I try adjusting my 3000 and 5000 numbers down to the negatives to try and lean it up a bit, or lower the fuel pressure in the middle number? Plugs are nice and dark, maybe even a touch on the rich side.

Also, I am burning alot of gas. I am burning through about 3-4 gallons more than the others in my group. I know that turbos burn more fuel and my riding style is a factor as well, but 3-4 more gallons in a day of riding? Am I too rich, or is this normal?

The ADA should fix most of your problems, well worth the money. Also put some negative numbers in the 3000 and 5000 settings.

BD starting numbers are very conservative (which is great don't get me wrong). It is not uncommon to lean out 5 to 10 numbers almost across the board. Once you get dialed you won't burn much more fuel than a stocker.

I would look at clutching before I leaned it out. I would check belt tension and put a new titanium spring in the drive. Maybe just a new belt will fix that problem sometimes.

on an 09 with the 010 pipe the numbers I run with an ada box are 3000 -5 -8 -8, 5000 -14 -14 -5, PSI 15 27 48 these numbers have worked great for me most of the time. but on certain days I do have to go up or down a few numbers on my lo and md

I have a 2009 BD PG kit with the ADA and EBC and I have been experiencing the exact same issue ( apparently that doesn't help too much in this regard)

I did foul all 4 plugs last saturday

I then slowly started leaning it out and watching my EGT's, and was at 15 30 42 by the time I was back at the truck, and I was still just slightly rich it seemed ... it didn't cure the bog at that 5-5600 rpm range under 1-2 psi of boost, but it made it less.

I was riding 9-10k too, almost exact same conditions.

when I unload my sled and start it i turn my 3000 lo to -15 and my md to -12 then head down the trail, after about 5 mins of trail riding the sled is nice and warm and the pipe is hot, I can go back up on the numbers. I've ridden all day many times with the lean lo and md #'s with no problem, I just found that with the turbo pipe hot it had a bit better off idle response and pull when I richen back up.
