ECU tuning for twin turbo engines?
 

I have a question guys, who currently tunes the twin turbo 3.0/5.0 engines, specs would be welcome or links.

:cool::thumbup:

The tuning may be somewhat specific by vehicle chassis. There are lots of tuners for the 335, and many of them then moved on to the 535. The usual differences were minor, they just had to get around to doing it and ensuring the codes worked. Haven't seen tunes yet for the twin turbo V8, at least not readily available, but if they aren't out now they will be soon.

Try these vendors:

Recommend you look at the Vishnu Procede, good reviews.

Installing a Vishnu PROcede to a 335 was a breeze. (They even have a video on youtube detailing the install from start to finish.) I was impressed by the quality of the product.

Dinan will be out with their software for the X6 50i in 60-90 days. They are in final testing stages.

Their tune will be a little on the conservative side but it will add 50hp and 70lbs torque

I purchased a crd tuning box from ebay, loads better torque better fuel eco and can remover for servicing, recommended:thumbup:
