Markus - Brits refer to the dyno as a "rolling road". I believe you are calling the street a rolling road. Rolling road and dyno are same.
I was suggesting that you tune on the street with your wideband first - which I think you are doing now.

I really can't wait when I can floor it. I was stupid to start building it in summertime. Car has been on the garage for allmost 2 months now. But I really hope that it is worth for wait...

3 hours is what ECU box itself is capable of, without laptop. If i connect my ecu with laptop and have a friend supporting me, then I can log it as much as I want ( I quess then it is directly related to the size of harddisc then).

At the moment I have set 10 logging points per second. But it could be changed. The ecu main protsessor can handle 16 Mips (milion instructions per second). You will note the difference when your engine is high rev and has to many mits to hanlde with. Tatech is capable of 13 000 rpm.
I hope thats the answer what you where looking for..

Well guy's
I had some tuning done with good friend of mine, we did it on the road not the dyno. It took around 8 hours of constant tuning work to get it running as it should, at least we manange to do 98% of the job. My cruising maps might need some smooth tune but it is really close to perfect.
I guess there are questions now how does it preforms after tuning, well Im getting smth like 1.5 bar of boost with 4th gear around 3200 rpm, @3500 im getting around 1.7 bar of boost, and @3700 it's smth like 2 bar. With 1st gear im getting max boost at smht like 4200 rpm, thats not too good, but ill surrvive.
Also at the moment my fuel pressure is set on 3 bar @ idle, that means that my injectors are smth like 550cc with that kind of the pressure. @ 6 bar of fuel pressure same injectors are 950cc so there is plenty of potensial on those ones. By the end of the tuning day we maxed out thos 550cc's so we could calculate approx HP nr according to that.
Turbo itself seems to be capable of smth like 30 psi overboost to the redline. I accidently even saw my boost gauge showing me 32-34 psi but this is not safe with stock head gasket so we took it down to 1.5-1.6 bar of overboost what im driving now.
I did some test also by tring to accelerate from 100-200 kmh. i did wiht forth gear and it took aroun 10.5 seconds to pass 200 kmh mark, so it could be another guess point for HP's
It pulls really strong and does the wheelspin wiht 3rd gear when it gets to 1.5 bar. Im guite happy at the moment but I know that there is some hidden potentsial when I install long duration cam (can anyone suggest..?.), raise the fuel and boost pressure a little bit. My goal from the beginning has been a car with 500 hp, 0-200 wiht 12 seconds, 300 kmh topspeed.
Next steps: platinium plugs, wide fire head gasket, intercooler vent holes, GT2 clutch installation, going on the dyno..

I didn't see any spec on the turbo in the text.
It looks like a T04E compressor housing with 4" inlet?
What sompressor wheel are you using?
Is it a 0.63 A/R turbine?

Great color on the 951 too!
