Dinan releases software for the twin turbo F01 Alpina B7 - +73 hp, 573 peak
is the first US tuner to release a tune specifically for the Alpina B7. This is great to see as the B7 uses larger turbos than the standard 750's. Dinan raises boost 4 psi, to 18psi total. The torque gain is about 100 lb-ft raising the total to 644. The price for this tune is $3,499. That is a bit steep for what we see as doing the exact same as their standard N63 tune, raising boost on the N63, which already retails for a steep $2,999. The $500 premium is likely due to it being an Alpina. Still, great to see a tune option for the B7 owners!
