Well I can only refer to what my tuning guy told me.
We spoke of the problem with smoke after removing the DPF.
And he told me he could control that with the amount of fuel he added. And he then mentioned that he'd only added 7% more with the mapping I was running now.
And I'm sure he knows what he's doing. He's been tunning both Skylines, Supras and Lamborghinis. All petrolcars though....
You are saying that the Bosh ECU can only go as far as to 600nm or?
Ive seen dynos from tuned 330d's reaching aprox 700nm??
