Alright, ive done some serching and was unable to find anything non subjective!

so please everyone tell me what you think1

My thoughts are extreemly lean!

this is a very aggresive tune using 101 oct.

plugs have that light tan color but also have a white resadue aswell. Im not seeing signs of detonation but it sure seems to be lean. I also run a very lean afr, whitch ill share once i get some feedback.

please no flames just honst answers

TIA

 

It appears to me that the two on the left are out of cylinder number 1 & 2 and they look a little lean. The other two are just about right. But from the angle the picture was take; the two on the right "it looks as if your correct about agressive timing" I dont know what your timing is at but it seems to me that it isnt buning perfectly...as if it may be two advanced.

Now all of this may not be what i see because it all depends on when they were taken out. Example. If you want to know what they are like @ WOT and full boost then make a 3rd gear pass at full boost and then turn the car off right away and pull off the side of the road and change the plugs out. And when you look at them then you will see what i mean. Also what is your timing and a/f/r at?

 

it's a little lean, but not that lean. Looks fine to me. remember the whiter it is the leaner and the blacker it gets the richer.

 

Not sure what timing is, heres the file of my af's

 

Are you using any additives or race gas. Normally race gas will make them cloudy white and additives like NOS octane booster will give it a copper color.

 

101 race gas unleaded

 

eep thats a lean tune

 

looks really lean to me
