Re: Anyone w/ Kelleners ECU installed in US

Does DAZZ carry the 'claimed 20Hp gain' ECU module from Kelleners? Has anyone have it shipped from Kelleners directly and installed here in the US? What about warranty issues?
Does Kelleners use factory replacement K&N filters with this module?
Your comments are appreciated,
Since I don't live in US, I can't answer the US related questions.
This SW does not require any K&N filter but you may gain one or two more HPs from that. The 20Hp claim is true. No car has "chipped" by Kelleners has not gained at least 20hp.
My car gained 23hp and 34Nm from this SW. Kelleners use a dyno to finetune the SW for every car and I have graphs from before SW. Both the effect curve and the torque curve is above the original curve all the way which means more power at all revs.
After the SW upload the car reached over 300km/h on level ground. Before those could only be reached in a slight downhill.
Note that it also removes the VMAX limiter and the throttle response is faster.
