kgamaseg, where do you insert the HHP gas? Before or after the turbo? I am testing right now with inserting after the turbo, to see if that could work better. The theory is that the hydrogen molecule is so small that it can escape through fittings and hoses that are airtight, so closer to the engine, the better. It is worth a try!
how did your engines exhaust go? does your engine have a computer box? i changed mine to 3 units in a series circuit and shifting @ about 1100rpms was no problem on flat roads (my engine usually knocks with the unit turned off at that shifting point) and i dont know how to fiddle with the ecu......

I put a Dutchman HAFC kit on my 08 passat 2.0T and it's giving me a lot hp, but the mileage hasn't improved.

I have tried to fiddle with the MAF sensor, but the car get most mileage without any change.

Yes, my car have a computer. But only controlled by a MAF, no ox.sensor. Exhaust perhaps a little cleaner..?
