Almost garanteed your not rich

Im NOT talking about the burning smell of a new exhaust, im talking about the smell of raw gas out the tailpipes since you dont have cat converters. As long as the eec is doing its job, your around 14.7:1 @ idle. Old plugs with some miles on them tell you nothing. 30's are what you need plans and simple. You dont need a tune for a little combo like yours. If you want something cheap that can help tune, buy a pro m remote optimizer.
