Default Spark plug inspection

Decided to pull my plugs today and give them a good inspection. I'm posting this to show what to watch for, as well what can be done.

It'* a bit hard to see but #1 and #6 are both a little black so are running rich. #3 and #5 are also a bit black, but not nearly as rich. #2 and #4 are both running good.

Any time you change your exhaust from a stock set up you change the flow rate. This will cause the front bank to run lean. This is where tuning software comes in. Trust me on this, if your going to be working on your engine this is truly the best $500 you can spend.

I started off with skewing the front bank to 1.0200, so 1, 3, and 5 all get a bit more fuel.

Here is what I have now

I started by skewing 1 3 and 5 to 1.0200 and leaving 2 4 and 6 at 1.0000 I then adjusted each injector a bit to balance them off.

Do you remember what the stock pulse width'* were? I'm not trying to be a pain, but this is good info and I want to get a better understanding of this and using my HP suite.

Pulled plugs again today, all looked good, but #1 was still a bit rich. Pulled another .5% off that injector.

Played around with the seesnake came today. Was disappointed that the camera will not fit in the plug hole. But I still was able to look inside the cylinder.
