What should I be running for fuel pressure on an 07 M8 BD RG turbo?
Also, are guys blocking the stock exhaust hole?

Fuel Pressure

XXXModRods Sells a real nice turbo vent that goes where the stock exhaust was. I have it and really helps get cold air to the intake.
You ever gonna bring that thing out here & RIDE IT??????? 
Ask whoever you got your numbers from what psi they're matched to. IF you use one guys PSI & another guys numbers, you can run into issues.

Yeah, were coming out the 26th and riding the 27th, 28th, and 29th of this month. We're staying in Kremmling and going to ride different areas each day. Probably Rabbit Ears, Buff Pass, and maybe Spring Creek.
I'm using Boondockers stock numbers to start with. The guy I bought the turbo from had it on an M6 so the numbers probably won't mesh well. I'll call Boondocker and see what they say.
The bottom numbers I'd guess would be pretty close, but the top should be a ways off.
Get your azz some numbers before you get out here!!!! You don't want to spend the trip tuning... and getting STOMPED ON by my little sally short track

I put a post on here awhile ago about numbers and never got any. I figured somebody would have given some good numbers. I mean a stock 07 m8 with bd rg turbo isn't a one of a kind. Somebody on here has to have decent numbers. I'll try posting in the m series section and see what I get.
Yeah, yeah, yeah. We'll see who stomps who.

Thanks for your response. But I have the older boondocker box so those numbers don't work for me. I have the 3000, 5000, 6700, 7800, 8600, tboL, tboH. The tboL and tboH numbers have -2, -1, 0, 2, 4, 8, 12, 18 to adjust.
try pressing right and left arrows down while you start the sled and see if your box reads supertuner mode?? if it does you should be able to scroll through the fuel menu until you get to psi L and psi H to enter #'s there and also check CR and OS #'s ??

I tried that. All I got was the stuck button command.
You can send the box back to boondocker and get the newer version. Most of the time they will do it at little to no cost. They have a pretty quick turn around also. The newer software is also much easier to use than the old set up. I have the new BD box on my RZR and it is much easier to use than the old style box that I had on my M7 before I did some upgrades and went to a OVS set up. Just a thought.....
What starting fuel pressure do you use for these numbers? Mine are similar but at 39 lbs of fuel.
I'm in supertuner mode..
Anyone?
