If you're considering a product to make adjustments to anything remotely impacts fuel injection, I'd like to play a game.
Please write down how you think your Sprinter's fuel injectors work.... just jot down your understanding.... high level stuff like "this is what a fuel injector does...."
Then write down how you understand a "chip" or a "programmer" or might improve the situation as far as you're concerned....
Then read this:

Now looking at what you wrote down, and after having read that PDF.... what are your thoughts?

Hey relax Jon, nobody is shoving chips or programmers down anyones throat. Companies need hardware to sell you or else most people wont bite.
What I was eluding to is how communities of car enthusiasts have dismantled most of the popular ecus and offer software for reading the ecu maps and altering engine perameters often times for free or a small donation. Even the Nissan GTR which was said to have an "uncrackable" ecu was cracked before they even hit US shores (by buying a JDM version and shipping it here). I doubt if MB put any roadblocks into their ecu.
Some of these guys (Mitsubishi, Subaru, NIssan, Mazda,etc. enthusiasts) are running dual maps on the stock ecu, one for pump fuel, and one for E85, with a switch on the dash to toggle between the maps based on availability. They also run ethanol content anylyzers to monitor the E85 because of differences in ethanol content from winter to summer blend requires a modification to the map, all on the stock ecu. Valet modes, gear dependant boost (great for different driving habits city vs highway), raised speed limiters, you name it its being done.
Think about it, you give a "tuner" $150 for a map, download it to your ecu. Drive and log the engines outputs and send the logs to your tuner, he sends a modified map back notating changes made (and you learn something about what he is doing) and you download to the ecu using your laptop and a purchased cable.
This is far better than a chips perameters that were set with a high safety margin for unknown variables (just like the OEM maps) like fuel type, loads, etc. etc.
It is widely known on this forum that the fuel we have in the US isnt ideal for the motor right? Why not modify the maps to run most efficiently on our fuel?
The sites beloved A.bittender is modifying maps on the torque converter, its a complicated thing (like diesel injectors), and was designed by MB, what could he possibly do to make it better?
Sure tuning isnt for everybody, and no we dont have what we need (tuners or software)to do it right now hence wishing we could get a few ecu engineers over here/interested to dismantle the thing. Diesel engine tuning, is diesel engine tuning, from that point on no matter how complicated the systems are its all just run by a computer.
Based on bikergars review I think I COULD be happy with the power. But not everyone has the same review as him.
I still would like a "scramble boost" button that gives me the 392ftlbs the poster above has with his Renntech for a limiited time frame (120 sec?) and only if certain conditions are met (oil temp, trans temp, etc.), besides running as effieciently and as CLEANLY as I can on a daily basis. Almost all cars come pig rich from the factory and from what I have seen of the EGR problems on these the Sprinter is no exception. Why not clean it up?
I think there is a big market for this, if you could save a fleet of vehicles like FEdex just 2 miles/gallon/vehicle worldwide by being tuned for the fuel in its particular country?
