Well, I am all for remapping, when it's done for specific reasons. But none of the tuners are providing anything to help me make an informed decision.
Considering that, all I can do is judge on face value and what different tuners have achieved with this engine. ESS Tuning have me sold due to what they have done, and continue to do. They specialise in BMW engines, and tune all aspects of them. Developing new kits (like the 3.4 Alpina one recently)... surely that is the best advert going, yet people ignore it and go for a cheap "bought in" remap.
I actually have a side line business/hobby in car tuning, remapping a fair few cars... some of the utter crap coming in on cars that have already been remapped is worrying. It does the job, but for all the wrong reasons, and often built-in safety margins are just totally removed, or made ineffective by de-calibration of finely calibrated tables (ie, fundamentally doing the job of £1 resistor jobs on sensors, within the ECU)... cheap and nasty!
I wouldn't touch any tuner who hasn't developed that map on a car themselves, and has many many hours under the bonnet of those cars, understanding how they work, and how they drive, and maybe why BMW tuned them the way they did in the first place.
I'd say ESS have that experience and background.
Again, I'm only suggesting that people ignore the quoted power gains and the price, as neither mean anything in the world of bullshit tuning marketing. Look to those who work with the cars and really do heavily modify them, those who specialise in them, those who have been doing it well and making money for years and years, for those who know how to really get the best from them, honestly, genuinely and reliably!
