Does anyone have any experience of these guys and the tuning box they offer for the sDrive 2.0i , they seem to be claiming good gains

Would love to know what the more technical of you think about this and any others you could recommend or advise to avoid. Thanks in advance Steve.

Not a fan of mail order boxes, prefer to take them to a tuning shop and talk through the options. Is there a tuning shop anywhere near you? I've used Corten-Miller before, pretty impressed with the service and outcome tbh (http://www.corten-miller.co.uk/) - they are between Boston and Skegness

Had one fitted to my wife's 1.4 twin charger beetle

Good unit

Made improvement to performance but not economy

It appealed because it's plug and play

Just fit to three sensors and it had a block if you wanted to remove the chip unit so you don't have to unplumbed it when it goes for a service

They are well regarded in the abarth community and the Skoda VRS boys

Hi

The JB4 for the N20 stage 1 has great reviews on n54 forums - I had an JB4 on my 335i - with dual induction kit - made it go from warp factor 7 to 12!!!

I am considering in going for the jb4 stage 2 on my 28i when it arrives - http://burgertuning.com/N20_BMW_performance_Tuner.html
