i believe that i read it is around 150 degrees difference between the DP and the manifold. regardless of the turbo cooling the exhaust, it will still be very hot. ;-)

here is my exact plan. my car is completely stock right now. i am going to monitor on the DP to get some base readings. mitsu would not make the car run dangerous temps when they offer a warranty, they dont want to be fixing blown engines from melting parts hence i wont have to worry about where i monitor them from, as long as they are constant. once i have my base readings for idle, WOT, and cruise. once i start modding and gain a need to tune, i will monitor the temps so that they stay near my base readings or slightly lower. i know running rich will make me run a little bit cooler, but only to a point. if i monitor the timing via a pocketlogger and watch my EGT's so that they resemble the base readings i got. opinions?
