How are you making 13lbs with a 2.55? I'm seeing 10.5 up top with a 2.50?
Either way, should be badass man!

boost
my set up might be different then yours
I have ls9 cam no overlap ,bigger cam makes less boost also heads and snout ported what your set up? I rather have 10 lbs of boost and more power when i upgrade to BTR stage 3, I think i will loose boost but gain power. |

Gmpp ported ls3s with ls9 gaskets net me 10.9:1 compession, 2 inch headers, untouched blower, and btr stage 3 pd cam.
The difference in our cams explains it

another factor is elevation. Houston is about 45' above sea level, whereas Findlay, OH is almost 800'. The BTR cam has negligible overlap (1/2*), so I wouldn't think that it would make a big impact on boost pressure.

I've been running this pump gas/meth tune for 9 months with no problems. I've got a smaller pulley for my race gas set up. The cylinder heads have never been off.

The real issue is past 20 pounds of boost, from what I hear from respected shop owners and engine builders, that's when you risk pushing water. You'll never get to 20 psi on a non forged bottom end, but the point is pay more attention to your whp than your boost.
