"I havn't seen what the factory a/f is but I am sure it's around 15.5-16 (a little rich) at idle and 14-14.5 at wot."

USUALLY stoichiometric is considered to be 14.7 (idle) and Wide open throttle runs tend to be around 12.0 I disagree with his above statement. I have a wideband o2 sensor ($800 dollar sensor that uses a TRUE wideband, not the $40 dollar summit racing sensor) I may throw on my truck to get some realtime readings but the ones listed above seem WAY off.
The part dealing with the hemi pulling on basically any car/truck on the road while in 2nd gear....total bull! I had a guy in a hemi trying to run on me one night after a motorcross event. We were both empty and I let him have the jump from about 30....low and behold I reeled him in and passed by 60.
My thoughts....
Basically what he said besides some I listed above is some great information.....
If you drive a hemi
