Can anyone tell me what the formula is for timing the amount of fuel out of my system? 1 gallon in how many seconds? I replaced my old BG400 system, that crapped out @e-town divisional, with a Weldon system, but still getting a miss fire or popping soon as I hit high gear. Never does it in 1st or 2nd. This is something new that just started happening. It'll sometimes backfire when I try starting the car, whether cold or hot. Very puzzling. All replies are appreciated. Thanks. Dave SS/ea #1355
