i have a 92 fox with a built 347 stroker and a paxton running 6lbs. of boost. i have stock computer and fuel pump still in it. i have a miss at mostly the lower rpm when you try to keep at a the same rpm for about 4 seconds then it misses. but when you get on it it runs good. my air/fuel ratio gauges stay in the green then it will shoot to red and start missing. What is the problem do you guys think?
