Hey Everyone,

I currently drive a 2013 BMW X3 28i and I'm looking to get the JB4 tune for it. Anyone have any experience with the tune or would recommend it?

for a 2013, near or out of warranty, a flash tune should be more ''precise and efficient'' than a piggyback. Also you can find flashtune around the same price or cheaper than a JB4.
Also, BMS are not open to help you if you have issue, I wouldn't recommend them.

If its not done yet, keep some $$$ to change the timing chain tensionner and chain kit. I wouldn't go more than 60-70k miles on stock chains.
I dont own a early N20, but I believe chain job should be around 3000-4000$ ?

I replaced the timing chain guides through my warranty when the car was at 40K. I also bought an extended warranty for the car and everything is covered up til 102K.

I've been looking for tunes but can't find any besides the Cobb. Any recommendations?
