I have just fitted mine up to my 07 and was not seeming to get some of the performance gains claimed by others, I have been talking to the guys at Steinbauer and Diesel Care, both have been very helpful so far. This morning I threw the old duck across the rollers and confirmed a complete lack of change when the trim pot is set at 100% until it reaches 3500rpm(the settings are 80% Min- and 130% Max+ on the dial as quoted by Steinbauer for future reference). The information I have is that at 100% setting on the trim pot and under load the module increases the PW of the injector to 150ms, when set at 130% the PW increases to 195ms.
This should mean that at WOT (Wide Open Throttle) the pulse width should increase across the whole fuel map, Dyno results this morning proved otherwise at 100%. However at 130% this was true and I had gains close to Steinbauer's claims.

The vehicle is stock with 200K on the clock.
Legend:
Pink – Steinbauer disconnected from harness, stock run
Green – Trim pot set at 100% (vertical pointer)
Red – Trim pot set at 130% (full)
Going back to the information around the injector pulse width and how the module changes that, all runs were at WOT so no progressive acceleration and when you look at the 100% trim (Green) it’s clear it stays at the factory load table until 3400rpm before altering the pulse width.
Other than that, the increase at 130% is reasonably close to the Stienbauer claims of 19.1%. My engine at 95RwKW is not bad for a 200K old engine, an overall gain of 17.8% to 111.9RwKW. Although the amount of un-burnt fuel is horrific out the exhaust at that setting. I will leave it at 130% and monitor the fuel economy over the next two weeks.
