Since early L-jetronoc models, any car could be made to feel more powefull and strong, especially down low and in the midrange, with 2-3 resistors.

I read your post and understand what you're saying. I machine code for a living so I "get it". I have tunes in my M5 and Z06. Believe me, I've never been a believer in PB devices.
With X5, it works great. There are people that have had the JBD PB for years with no issues.
Have you driven an XD with a PB?
