In my never ending quest for knowledge I have a couple of questions,but first, thanks Hoot for your article on EGT probe installation. I heeded your advice about blowing chips and still have 20/20 visionhttp://www.dieselplace.com/forum/smileys/Big Smile.gif and a completely working J/A. Now on to questions...EGT what is the max for a stock..kind of...D-Max before destruction begins? Also what is a "Jake Brake" and how does it work? Thanks

1300 seems to be the accepted max for extended periods(more than 20 seconds)

What would make it go up to 1300 degrees and or the mods to lower the temp if you wanted to put more power onto it. Air intake,straight pipe, Box?
