Racechip GTS or JB4 X5 40i
I know couple of members have Racechip installed, anyone is running JB4? What's the pros and cons on both of them?

I'm running JB4 and I think it's great. The power increase is smooth and the app makes it simple to log or switch maps on the fly. I've used the JB ever since JB1 (later jb2 & jb3) when the N54 (335i) model was released. The guys at BMS have always been super helpful. The install is simple and straight forward.

I was told by several tuning company's that the tech in the race chip is much better I had an RS7 before this and I ran jB4 And has some issues Also JB4 support sucks It's all preference at the end of the day I have gotten major gains from the racechip gts
