I spoke to a guy at Diesel Dynamics and was told to test my truck to see if it could handle bigger injectors without running too hot. I have run it on #6 with about a 7K load up a hill at WOT and cannot break 1000 degrees. Is there anyone running a Banks unit that is running hotter than this and if so how hot are you running with and without a load?

 

I am setup right on the #3 hole of the manifold so it should be pretty close to one of the hottest points.
