Run times on Dastek were an issue as they were fixed rpm/sec acceleration and load applied as far as ecu was concerned was quite different to real road... maybe they have changed this.
top end fueling is rich, but EGT's at that level is also a factor... (as well as the code which is on the car - which I do not use anymore for stage 3 btw, due in part to this kind of top end richness for no good reason)
Badger wagen is running 12.0-11.5 top end fueling... 9000rpm, 35psi boost as a
guide to what produces good power.
