Hey Orb!

I am getting this done in the next month and was wondering:

1) How does it perform at launch if you floor it? Do the tires spin from too much hp? My turbo tuner was almost redundent power wise from launch since the wheels didnt know how to handle all the extra power.

2) Did they do the upgrade at your BMW dealer or did it have to go to Dinan and therefore make your car undrivable for a few days while the ECU was being coded?

Thanks for the info!

should be interesting to see how the auto tranny holds up in the long run with 570 Nm (421 lb-ft) of torque when the tranny is rated at 450 Nm. hopefully the tranny can hold much more power than 450 Nm, but we all know how vulnerable the E46 330i auto tranny was. it was rated at 300 Nm, and running more than 400 Nm could lead to trouble.

The tires in 1st gear spin fairly easily and I do have a Quaife LSD. Shifting into 2nd at full throttle the rear does become unsettled while hooking up and bit with 3rd gear. I suspect it the same with the PROcede v1 as well and more so with v2. Before the upgrade i couldn't spin the tires in first gear that often on dry roads.

I went to a BMW dealer to have this done at took about 2 hours as it was there first time with the flash.
