can someone read my plug? Its from my 02 camaro ls1 cam only. I just installed a nitrous outlet plate kit 78mm. Plugs are gapped to .35, 5 degrees timing pulled with lnc2000. Bottle pressure was 930, 125 shot. This plug was put in and has a quick burnout and a full 1/4 mile with 2nd-4th being sprayed shut down immediately at end and pulled. I know its only one plug but its hard to change out 2 sets of plugs on the street, also I didnt the cut the top off yet, I will if you need me to.

try brushing off the ground strap w/your thumb and cut the plug so it can be seen.

I'm not sure about the mph, I haven't tracked it yet. I'm at work so ill post a pic of it cut tomorrow. I thought n2o outlet kits were notoriously fat? Maybe my stock pump isn't keeping up, the car only has 52k on it, so I thought I would he good there. The car has about 20lbs through it like this at the moment.

Its a plate kit, 57n 33f, plug was pulled from cylinder 3. I can't tell if I don't have enough heat in it or that's the timing mark at the base of the strap. If it is my timing mark it looks way aggressive and i need to take more out. I don't know what my base timing n/a tune is. I'm not looking to pull every hp out of it, I just want a safe tune being its a street car, and I don't want to have keep pulling plugs. I want to get a conservative tune with a 150 hit. Maybe once I get more familiar with nitrous tunes a 175. I'm upgrading my fuel pump shortly. I don't have a wideband yet, I also don't get to track much. So this will be all on the street and reading the plugs. All the help is appreciated.

Too rich, you will see a carbon ring (dark) around the base of the plug. You don't have this. No need to even check the porcelain in this case, its rich.
If the base fuel ring disappears, like yours is, I would be looking at cutting the plug for analysis.
Too lean, and you may see a blueish tint to the base.
If I had to guess, would leave the spark as is, maybe reduce by 1 degree, then add a little fuel and see what happens to the ground strap and power.
Without seeing the fuel ring, not much else you can do. That is why I asked about your MPH earlier. Good indicator of power anyway.

This is my first time cutting the top off one. If there was a fuel ring it was where I cut it. I don't see one, but I also don't know how to read it. I also double checked the gap with a feeler gauge and the gap was .38 the dial gapper will never be used again.

I can't see a fuel ring. damn. are you sure you had the nitrous on? this plug looks like an n/a car that hasn't run for long. one thing is for sure, your engine is not burning oil and runs clean.
