Well, a little frustrated, but all is good now. We melted all 4 spark plugs the other night with too much NOS, (197rwhp and 96.8lbs tq). I could go in and try to put a little more fuel pressure in it, but I'm tired of messing with it. 159.8rwhp and 76lbs tq on motor is the outcome. We went from a 40 shot to a 60 shot and gained another 10hp and 4lbs tq, (176 to 186) and I put the PC3 to full high on the high bar with no difference thinking it might not be have enough fuel. I backed it down to the 40 shot to stay safe, (which is 8hp less on NOS than I ran last year). Guess the higher compression isn't liking the NOS as much. It did gain 6hp on motor, so I guess it was worth it. I probably need to switch to a PC3r and pull some timing out, but I guess that will have to wait.
