+1 on cold stumble. I thought it was only something wrong with my car.

And yes, from 1800 with stock rubber you should be MELTING the tires. I have 285/30/20 NT555's and I can rip em from 1800.

I've decided that it's just something like that I have to wait for my plugs to warm up (even though they are still the stock plugs)..

If anyone has any info to the contrary, I'm all ears.. Oh, and yes, 20 inches of vacuum is about right. The only time I see ~25 is on decel/downshifting..

Well, I am not sure if the mpg is fixed or not, but I reinstalled the tune, then I disconnected the battery and let it sit overnight. Then this morning I let the car idle for abput 15 minutes to relearn then I began driving the car and after abput 15 minutes of driving it now says I am getting 14.3 mpg. Of course a little more time will be needed to see if it is a fluke. But as of now it looks like my mpg are back up. Now tomorrow I get to see if my cold start issue has changed, and then the fun part. I have to find a backroad somewhere and get on it to see how it reacts.

Give us a detailed description of how the power feels when you get on it. I just ordered the stage III kit as well and am wondering.
