spark plugs
i got a new tuner and have been playing with WOT air/fuel. first started 2% richer plugs look like this and i am up to 6% now and plugs have not changed. 6% felt like it slowed the rpms down but to me felt like it pulled harded. this is all off motor passes no nos yet. and i would turn it up in 2nd and hit 3rd and go to about 5000rpm wot and let off and kill motor and coast in at buddys house and pull a plug. what does this plug look like to u guys?
