WOW - 1600 degrees -
Where are your probes ?  - Mine are 2.5 " from the exhaust port  From all my 
research - Much over 1400 degrees and I was told you should start being 
worried
Plus my plugs, tail pipe and dyno pulls with a O2 sensor all show that is 
where I should be -
Anyone else seeing those kind of temps? -  here is a good link
