Hartge ECU Tune for US 535i ?
11 35 2306 J Engine conversion
for 535i (based on 225 kW / 306 hp /engine N55B30 Twin Scroll Turbo)
266 kW (362 hp) / 5660 rpm 480 Nm (lb-ft 354) / 2950 rpm
Is there a US version of this? I e-mailed them but they responded stating that it is only for Euro spec cars.
What is the difference?
