For FI, .035 is good. .050 will be too much.

I just took mine down to .028 to address a breakup on high boost.

cool thats what I thought. I was hoping I wouldnt have to pull them all out just to gap them. I have been having missfire problems but I think its (hoping its) tune related. its hard to make positive adjustments at this point because Ive modded too many damn things so the computer is seemingly confused no matter what I try to adjust. at this point Im just glad Im not getting KR. thanks again. back to the drawing board. ~Guy

Depending on dynamic compression and many other variables I would start at about .028-.030 at 15#. Maybe even a step colder with more then 15psi on the common setups around here.

Are you sure the missfire isn't fuel related? By the looks of your setup, I'm surprised that a single walbro and 42# injectors are getting you enough fuel. I maxed out my single pump and 42's on the stock block an 8 psi. I hear you on the computer seeming confused...I went through a lot of the same thing when I put mine together.

I agree, I'll be running one walbro and 42's on my stock block up to 8psi and pray the duty cycle isn't too high. I got 60's but are the shorties for the L76 intake so can't use em. I think I should be ok up to 500rwhp and where I want to be until I get my 370 in. 12psi on one pump and 42's is way past safe imo.
