UPDATE!!! As I promised I would do.

I recieved my computer today from Overkill. I installed it and was on the road in 5 minutes. The thing is a complete animal now. Before I installed it I was having KR and it just wasn't running very well. I had a lot of mods and needed the tune badly. First of all I had 0 KR and the most I saw pop up on the scanner at anytime was .3 degrees for a split second. I got out on the street and I loved the way it shifted. It is smooth and quick and there is no loss in power between gears. I don't know how accurate the Aeroforce is for horsepower but before the PCM it was reading 290-300, now it was reading 330-350 if it is an actual reading I'm sure thats at the crank. Overall I'm completely satisfied. It took a little while to get it but it was worth the wait. OH and my mpg were reading about 3-5 mpg higher on city and 1-3 higher on the e-way.

Now I can't wait to get the 3.6 pulley installed, it is sitting around calling my name. But I'm going to wait till springtime for that.

Sounds good I have one sitting in a box for the last couple months tuned for a 3.6 but, I have yet to try it lol and I bought it off the b/s/t but need to have it tuned again by him since it's only for a 3.6 and no other supporting mods.

I bet it would still work for you. Just try it out. Mine is tuned for a 3.6 and i'm running a stock pulley for now. It still runs great and my mpg's are fine.

hopefully you don't get all the KR back when you put that 3.6 on.
How much did you pay for it? I remember you told me in one of my post i should get one, because i have close to the same mods as you and am seein ridiculous KR.

I paid around $100 I think. It was $200 something after shipping but there is a core fee. I have zero KR right now so if I install the 3.6 and I do have knock I'm going to just go back to stock. The only problem you might see is running a little rich but if you are seeing a lot of KR like I was you may just be running a little lean right now so it wouldn't hurt to try. It took me no time at all to install so it's worth a try. If it starts running funny or doesn't react right just put the stock back in.
