Dinan Software upgrade vs PPK1 upgrade???
So my question is what are the big differences in the Dinan Software upgrade vs the BMW software upgrade. I know that the Dinan is 2000.00 cost for the service and the BMW is @ 1000.00. What are the biggest gains from one another? I think Dinan is 355 Hp and 400 tq. Not sure what the BMW is? Just want to hear from people that have experience with these...Thanks.
By the way I have a 2011 BMW 335i with the N55...
