I wired up a small 40 wet Shot for special occasions, and been using the fuel noid for extra fuel when not spraying to run a little more boost. It's when I try to run said 2 more lbs of boost, when the afr's go lean after the 2nd hit, if I back down the boost to where I don't need the fuel solenoid everything it's fine. Prior to this it was running fine on that setup for a long time...I changed the fuel solenoid already, microswitch and arming switch all new, I even tested the system after she starts running lean, by removing the line going in the intake nozzle and it does spray...

I was wondering if there's some sort of sensor in the intake tract that has taken a toll with the meth and fuel going through it and slowly giving up???
