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?

looks rich to me. Is that a new plug?

no its not new. maybe 10000 miles on them. so u think it looks rich?

put some timing in it

and some brand new plugs

i looked everywhere sat for some plugs and the parts stores was only showing stock heat range. hell a guy at advanced DOWN HERE IN ALABAMA can pull up a chart that will show heat ranges. i will get some and may try to get to the track thurs.

get it right! lol!

yea i may be ready to run you off motor!!! we will just leave the bottle off for the light work:jester:

what ever you think! what r your best quarter times!

my best off motor was a 13.61 and that was spining bad and a long time ago! got a few things changed since then. and on the spray i ran 14.19 at like 111 mph lol.
