That's great! I'm surprised (and jealous) that your EGT is that low... mine teeters near the danger zone right around 1250 F and I have to watch my throttle application to keep it in the safe zone. I'm curious, have you measured exhaust pressure versus boost/RPM? Also- I'm pretty sure your pyro is in the same place as mine (pre turbo)… when you floor the pedal for 10-15 seconds in a higher gear, doesn't your EGT spike to 1500+?

02-06-2020, 11:38 AM #22it does go tp 1300 in overdrive but not with the tc unlocked. Are you using overdrive? The om 606 likes rpm and with the 24 valves, it breathes nicely. EMAP is staying well below the 1.5 factor at 2500 mb and yes my port is pre turbo. I am straight piped right now. What boost pressure are you seeing the spike at? If it is at above 80% throttle then you should decrease the fuel request there or request more boost. Let the DSL1 help you. Don't rely on your right foot. I know a good rule of thumb is to increase the boost at points of high egt if your turbo can make it but we have to look at the limitations of the oe IP. I'm trying to stay below 2500 mb. The GTA 2359 vlk can easily surpass that. Remember the DSL1 is only producing 1500 mb (1.5 bar) boost at 2500 because its' indicating psia. If you ask for more, you may damage the oe IP. I see why folks are always looking for bigger elements and turbos. I would like to know if there is anyone stateside that can put larger elements in our pumps. we can chase those lower egt's but water/meth may be simpler and you know the DSL1 is programmable for it if we do.
