Anyone any experience with getting a plug in tuning box for the 440i

I have seen one on RaceChip that gives +68bhp and +70nm of torque for £269 but I would ideally like to get the car over 400 bhp if I can.

any advice appreciated and feel free to PM me if you don't want to say on the forum.

Thanks.

A JBL piggy back tune should get you close to that figure. Not sure if they are available in the U.K. But there should be something similar there if not. You can also try MPPSK. The performance gain isn't much on paper but may be more than you think in real world.

Best option is the JB4 stage 2 for most power and features

We also carry the Jb+ which is a quick install boost controller for stock cars

Isn't the jb4 stage 2 for the N55?

In the UK I would look at Rebellion, MSL and DMS.

I've got a Racechip in my 640d and it's single connection and a bit average.

I'll be going to Rebellion once my car is run in. Oh and my car will have the MPSSK too, but I am looking for 400-420bhp.

We offer JB+ (stage 1 quick install) and Jb4 stage 2 for the B58 as well
