Pics of my plugs... examine please!
They all looked the same which is good. I've only put about 500 miles and two bottles on them. They do have a very light Grey color with very minor speckling(you have to look very hard) but only on half of the porcelain, the other halves are white. Also, I don't see any issues with the ground strap. Do y'all think I'm running a tad lean. I run 110 on the 150 shot but I haven't sprayed in the last 150 miles or so. All the examples I've seen of plugs in a lean condition are much more discolored and have rounded ground straps. We data log often and the A/F always looks good.
Should I bump up the fuel jet? Your opinions!

the only way to really examine the plugs is to make a pass down the street, strip, etc. then **** off the engine immediately, and I mean immediately!!!! (as in while driving) then, check the plugs.
On these cars, it's not that easy to check plugs, but often times, you'll see a drag racer on the return road checking his plugs.

British tuning method FTW! Be sure you don't lock the wheel when you shut it off @100MPH
To the OP,
Seriously though you will need close ups of the plugs for us to get an accurate picture of what is going on. You did not mention if you went to 1 step cooler plugs and what fuel you are using.

Color on your plugs is pretty descent

What heat range plugs are you using? Stock range? 1 step colder? Based on your mods, looks like you got considerable extra power going.

Data logs are just not a good way to tell if your plugs are doing fine or not. Someone already said it before. Take a car for a hard run, shut off the engine immediately, pull the plugs and examine them.

One step colder. I'm going to the track in a few hours so last night I decided to check the plugs since I had the time. The ground strap and color looks.
We pull 2 degrees on the 150 shot and run it a bit rich on 110 octane.
