hello all, so now that i got all the bugs worked out of my 13bre big single fc its tuning time. i have put about 2000 miles on it at a rather rich upper end set up. found out that the motor is over injected so i turned down the stage injection across the whole map. now the car will pull even though its rich as hell. anyways what i need to get a idea on is what all of your cars cruzing speed EGTs are. ie, 50 to 90 mph wich is like 20 to 28% load in my car from 2500 to 4000 rpm. right now i canot seem to get them below 1400 deg when im above 60mph. 1200 below 60. the map is 32 deg timing in this area and them motor is a street port intake and somewhat race port exhaust due to the turbo. the motor has 13b RETT irons ported large street rotor housings are s5 t2 race port with slight over lap due to the irons. i didnt take much more then .010 thou of the roof of the rotor housing. ecu is a wolf 3d v400 with 4.72 software turbo is a masterpower MT45 manifold is one of my own short runner 60mm and wg is a ITS progate 42mm boost is set to 15psi currently. thanks all randy
