Hi Stan,
I was reading about Dinan upgrades when I came across your comments. I have a 2006 X5 4.8is and thinking to install exactly everything you listed except the exhaust. I would like to get your opinion in more detail regarding your upgrade and especially the struts brace.
My plan is to get CAI, throttle body, engine software, and strut brace in one shot. I really appreciate your help.
Thanks a lot,
Kevin
