740 ECU Tunes

I have been looking around for an ECU map/tune for the F01/F02 740.
Although it is the N54 engine its is slightly more powerful than the typical N54 in the 335, so most tuners don’t have the 740 listed along the cars with the N54 engine that they tune.
Not sure if the difference is only software or hardware as well.

Here is what I have found so far (Updated):

Hartge: 390hp http://www.hartge.de/e/bmw_motor_5266.html Price approx 3K

Nowack: 351hp http://www.nowack-tuning.de/chiptuni...0i-240kw-326ps

VAC: 400hp http://www.vacmotorsports.com/catalo...d-x-series.htm

Kelleners: 392hp 480N.m price approx 2K http://www.kelleners-sport.de/b2b/in...vid=202&cat=28

Hartge seem reputable but the price is quite high?
Nowack doesnít seem to be increasing the power by much and the their email replies and site seem to be German only?
VAC donít know much about them and their reputation with BMW tuning

Does anybody have any additional information?

Hartge is a reputable BMW tuner. Check with Evolve (UK based company) too.

most tuners saying the f01 ecu is locked but they will sort it out soon .
i have raced 2 750s from 0 to 100 mph plus and both times it was neck and neck at times i felt the 740 was faster. although mine doesn't have all the bells and whistles like night vision and etc. I'm site with chip the 740 will smoke the 750

Got a reply from Kelleners and they confirmed the above 2k price range.

That is a good option.

Is it V1 or V2?

Does anyone have any experience with VAC?

Their approach seem different from Hartge and Kelleners (and their price)
hope it doesnt have any issues.

Went with the V2. I have been building high end high profile show cars for over 11 years. While the F01 will just be my daily driver I know of VAC and they have a great reputation.

Did you install the VAC on your 740i? How did it go? I have the 2011 740i also looking for adding more hp to it. I wonder why Dinan don't have nothing for our car, in fact they are quite expensive. Can you tell me more details on the VAC you bought, is it easy to install and did you do any dyno test to check if this thing really work.

thx a bunch.
