Kinda has a green tent i think. There black at the bottom & clean up top. How do i fix that? Fuel or timing? 150 shot on br7's

How much driving on those plugs? You really need fresh plugs at the track for one pass, click it off at the line, pull the plugs.

Its not my dd.There is some driving on them not sure how much they been in there awhile. I put a new set in last night & thats what i was going to do.

Yah, that's a useless plug picture.

Looks like your idle/cruising tune needs to be leaner also, because those plugs are richer than Bill Gates.

Pics are useless for nitrous tuning.

Read, research, repost pics....

what timing are you running and which jets? We need to get you in the ballpark to start. Your plug looks way off.

Im not sure on n/a timing & will ck on jets. Everything was adjusted when it was on the dyno & its been awhile so i dont remember. I had the motor tuned with tr6's in it but when i go to a br7 or br8 it wants to load up a little seems like. Would the n/a tune be that different with a colder plug? Another ? is i can run a tr6 plug & car will run around 7.05-7.15 on motor. Put a br7 in & the best i can get is 7.35-7.50. Would like to run br8's all the time so should i get the tune redone just for that plug?? Thank's

Those plugs are useless for nitrous tuning as others said.

It also looks PIG rich at idle and cruising.

Lean it up at idle and cruising until it's in the 14.2-15.0 area to help keep the colder plugs clean. I am able to drive on B8EFS just fine on pump unleaded, but with leaded fuels it doesn't matter how lean it is it will still load up after a while.

At idle every car will want a different afr value as different cams pull different amounts of vacuum and if you lean it out too much it will get what is called "run on" where the cam never drops back into a lope. It takes a good ear to find that sweet spot where you cam wants to idle at, but leaning it out will help keep them cleaner.

I need to get a wideband so i can watch it closer but im just not crazy about it reading it on one bank. I just started working on it again. Im prolly going back in a week or so to my tuner so he can adjust on it. I know alot of u r really good about reading plugs & geting the tune dead on so i was just wanting some opinions on it. Hopefully i can lean it out some & get some power out it. Thank's

As you lean it out watch the heat on the strap and the timing mark as it will advance with leaner afr.

Good luck!

I have B9EFSs in my car right now, but I have 11.7:1 compression. I don't drive it much except to the track, race and back but they are fairly clean. By running 8s, you are going to be ok, but you are going to lose n/a hp.
If you plan to keep the 8s in there anyway, tune the car for 8s, then adjust the nitrous jetting for nitrous fueling.
