I have an 08 m6 with an aerocharger 53 and a CPI pipe. It's running 8lbs on a 50/50 mix of 110 and 100. It runs good through low and mid range with my afr between 12 and 13, every time I open it all the way It cuts out and my afr shoots up to 15 to 16. I raised my fuel pressure from 38 to 42 with no success. My regulator is a 2/1 and pegs the fuel gauge at 60. It has an attitude box on it that I richened the top and the boost all the way and it still leans out. Help!! I'm new to these and don't want to burn it down.

Who's kit is it and how many injectors are you running? Maybe you can't run 8lbs. But we need more info

Yep, either the boost reference hose or your red/blue circuit is set too high.
It's all a custom set up. I've checked the boost line and lowered the red/blue. It has stock injectors. I had it at ten psi and took it down to 8 thinking I was running too much boost. I need a green spring to go any lower
May seem odd, but find someone who can plug in and read/ program your attitude box. I was having the same type of issues. I had all my fuel cranked up, and even high fuel pressure, and still couldn't fuel 5psi. Turns out my box was sent out with a 4 injector program in it, instead of the 2 injector setup that I needed, and had the harness for. Spoon, who is on here, from Canadian Power Machines, was the guy who clued me in on that. Took it to him, he had er figured out and riding happy in no time at all. Hopefully your fix is as easy as that!
The blue light comes on at about 1/8 throttle and stays on through the whole band. I'm going to check the injectors. I may just take the box to Derek at attitude and have him check it and update it. I have had it out about 4 times this year and it's done it every time. I changed plugs first thing. I talked to Garr at Ovs and he said take the cutler fuel pump out and throw it in the garbage and put a stock one back in it. Have any of you guys had problems with these?
