I'm sure many of you are aware of the addition of my ported blower, well I decided to go ahead and change the plugs while I had the blower off! I found something quite disturbing. My number 8 plug was fried! I never heard any detonation or anything. It was the same cylinder that fried a plug last time with the Diablo tune. Is it possible that the injector for that cylinder is stopped up or something? Any ideas on this?

could be the flow on that injector is down for some reason, but also the diablo tunes are known to be aggressive. you may want to put it on a dyno, you might be running on a ragged edge tune.

Well, I've switched from the Diablo along time ago so that's not it. I use SCT/ Terry tunes now.

i think it has something to do with the NUT behind the wheel

If the rest are nice and dark I would check the injector and cylinder in general.

How would I go about doing either of those?

Pull the injector and replace it or have it flowed on the bench. Do a compression test to make sure the valves and seats are happy.

How much should the compression test read?

How much should the compression test read?within 5% of the other cylinders..
but a leak down tester would probably be better

Probably about 100-125.

Can you PM me or post how much you would charge to do all of that?
