I recently ordered a 2012 Alpina B7
Dinan Software ECU upgrade
Dinan Stainless exhaust with stainless tips -
I have not had a chance to run dyno on the car but I really want too -
When I ordered the Alpina, the BMW dealer gave me a new 750 for 6 weeks to drive, it was a 2012, 400 hp - Its extremely noticable after the Dinan upgrades and I suspect you would really notice these enhancement on a stock 750..
Personally I would not worry about the extra wear, you wont get any credit for tuning your leased car but I believe these engines are meant to drive hard and the Dinan tuning wont hurt anything, in my opinion, has anyone ready about a recent dinan tuning mod that has caused engine problems, The warranty is honored and these engines now days are pratically bullet proof. tune it and run it hard
