Plug Color??? how does this plug look guys?personally, i think it looks a little rich.this is on a 150-shot for a few months now.maybe 4-5 bottles on these plugs.what do you guys think?
plug reading It does look slightly rich but not bad.
You can't really tell how yuor engine runs at full throttle and on the bottle by that plug though. That plug is showing you how your engine has ran for tha past couple months, which was probaly a lot of traffic, and highway driving. For example: it could be dangerously lean while spraying but a little rich at idle and that would give you a plug that looks like that.
Put a fresh set of plugs in and do a good nitrous pull and shut the engine off imedeatly, pull over and pull a plug and look at it. That is the only way to read a plug to tune for nitrous.
