1995 k1500, 5.7/350, long tube headers, true duals straight piped with resonators, bypassed intake silencer and added salad bowl intake spacer. When running k&n air filter, seems to be getting too much air and backfires through the intake. Is there any way without having to tune ecu, to get the truck to run more fuel or at least balance itself while having the maximum amount of air possible. Typically happens around 2500+ rpms. Maybe a O2 sensor signal modifier? Could it possibly be a timing issue? Thanks.
