My first guess would be plugs or bad gas.

I am almost due for the 30,000 spark plug change. I also recently filled up with some b.s. 10% Ethanol 93 Octane in VA Beach but by the time I noticed the sticker it was too late.

The Latest Super Chips update apparently lets you data log the engine ping sensor. There were a lot of new interesting items available for data viewing also. I have just updated this week, but I do not know how long it has been in there....
It is worth a shot.

Did the data logging: Knock Sensor 1 and 2 both measured volt range between .80 and 1.10, fluctuating. I've also notice a whistling sound that is coinciding with the sound of my exhaust but sounds like its coming from the engine. Any advice would be good advice, within reason...

On a side note about the above concerns of mine: every shop, dealer and fabricator in my area has refused to give me any help at all without first requiring my committment to some servicing on their part. I feel like I'm getting jilted. Why can't any of them give me some advice over the phone?

I'm thinking I need new plugs and there is a vacuum hose loose or some other kind of hose. I'm getting it dyno'd tomorrow and they said they'd take a look at it then. I was going to have it dyno'd anyways. I will also be having the 30,000 mile scheduled maitenance done Monday, I think that should clean it up nice, real nice...
