Just remapped my G11 740d B57 engine. Stock 320hp, now 380hp and 750nm. The car was already fast but now its properly quick for a 2 ton luxury sedan.
The best part is the smoothness. You barely feel the extra power, it just wafts along faster. Perfect highway cruiser.
Anyone else tuning their 7 series?
Tuning a 7 series is the ultimate sleeper. Nobody expects a luxury sedan to be that fast. Love it.
The 740d is the perfect sleeper. Nobody expects a 7 series to be fast. 380hp and 750nm in a car that looks like a chauffeur vehicle is hilarious. I love pulling away from sports cars at traffic lights in complete silence and comfort.
The B57 quad-turbo in the 750d is even more insane if you can find one. But the 740d with a tune is the sweet spot for value. Make sure to get the TCU tuned as well - the stock gearbox calibration on the 7 series is very conservative and smooth. A TCU tune makes the shifts faster and more responsive without losing the luxury feel.
