changing out the fuel solenoid will not increase your fuel pressure, that is definitley not what is going on. your A/F ratio seemed pretty good last time around, if you bumped up nitrous pressure from 900 to 1050 without changing the fuel jet then you are leaning it out. So you wouldnt want to do what beer did in going with a smaller fuel jet. In his case he was running slightly rich and wanted to get the A/F up a little. if you peaked at 13.9 and leveled down to mid 11's on 900 then you are in a good range. Since you increased the nitrous pressure you need to compensate that by increase the orfice size of the fuel jet. I think that will get you closer to the number you are looking for
If that's the case, then if I just wanted to get the number I was looking for, it sounds like I should just put the jets in that corrolate with a 200 shot, rather than a 150 shot. I just always thought the the Nitrous Outlet plate was rated at the wheels. Judging from my numbers and from Beer's numbers (he gained 114 at the wheels on a 150 shot), that doesn't appear to be the case.
