Hi guys

Has anyone bought or heard anything about these?

N62B48 DirectFlash Performance Software - ESS Tuning | BMW Tuning Parts | BMW Racing, Tuning, Aftermarket, Performance Parts | Engine Power Chips | Performance Upgrades Chip

I'm looking at getting one as I'm a bit disapointed with the performance of the X5 4.8. I also want to get the auto change charactistics changed...the hanging in gears going up hill is rediclulous. Has anyone had any experience with this?

thanks in advance
