Been running this tune for a while now. It does turn on the Check light due to cutting back the egr a bit too much at high altitude. Rev limit is bumped up and I have the trans shifting at 3500rpm on most shifts. Still fine tuning that.
The actual mm3 never hits the commanded amount of 120 or 130. Most I see is about 101. All timing tables left stock but fuel pressure turned up in mid RPM and pulse width only increased by 5%. Boost tables might be a bit low ? Also wonder why the factory lowers boost leval at high altitude but they seem to add a bunch of timing to compensate. The log was done with Re-gen active, when it is active and you lay into it hard it seems to hesitate just for a second and now that it's cold out is seems to puff out exhaust quite a bit when you stand on it from a stop.
Comments and criticism appreciated.
