I checked out the Kleeman site.. Hope I hit the wrong page. The closest thing to a price i could find on their site is 795 Euro for an ECU upgrade... ??? Kleemann - ECU upgrades for Mercedes-Benz and AMG engines
Pls tell me I screwed up.

Speaking of $$...
I agree with John regarding the deposits and amounts now required by BEGI.
I have absolutely no doubt about the quality of product they would produce.
However, I don't know of many cases where a business can pre-sell (and receive virtually full payment) on a product that hasn't even been prototyped.
Let's face it... money's tight all 'round these days. Things are not much better north of the border either.
Personally, I just think it's a bit much to ask for all the money upfront.
3600
+ 500 ? shipping
+ ?? customs
+ ?? Kleeman
+ ?? MB engine cover ...
+ my time / labour for the install may equate to an SRT/6 being the answer after all. ....which is what we were trying to avoid in the first place.
BEGI hasn't given any concrete details on the system itself... it still only exists in the 'Ether'..
I'm not bailing out, but I am apprehensive,and am questioning the validity of this path to more power.
...Just my thoughts at the moment.
