N54 JB+ Plug and Play Tune
Hi All,
JB+ TMAP sensor piggy back tune. I had this fitted to my 335i and it made a nice improvement.
It’s no JB4, MHD or Flash Tune but it is literally plug and play. Simply disconnect the battery, let the ECU’s go to sleep, unplug the TMAP sensor at the back of the Charge Pipe and plug this in line.
It tricks the TMAP sensor to give the car between 1.75 - 4.75 psi of boost which is adjusted via a little dial inside the box. There’s a min and max, I ran it at 50% with no issues and a noticeable boost increase (I was running Injen DCI’s and an atmospheric BOV so it was easy to hear the difference). Some people out there go for max but do experience issues.
It comes with fitting instructions.
£100 + postage or cash on collection from Kent. PayPal friends/ family or buyer to pay the 3.4% + 20p transaction fee for goods/ services.
Thanks.
