Hi I have a 525Td it has a custom intercooler and the chip has been mapped specifically for my car and on my car it has a standard 5 spd box and a 2.64:1 diff. the engine produces 190 BHP but I'm not sure of the torque increase but it is significant.
I have a six spd box from an e60 BMW530d and a lsd of 3.23:1, I intend to fit; the gear ratios in both boxes are the same with 6th gear being 0.8:1.
can anyone advise me if lowering the diff gearing will provide better driveable acceleration across the range or is the higher gearing as standard the better option?
regards Andy
