Hey all,
Couple of months later the car went on the dyno and came of it in one piece !

But one day wasn't enough so i went back another day for the last touchups.
this is taken at day one, the second day we tuned the higher revs and pushed the torque band just a little bit wider. but in general there must be a restriction, probably the stock Punto gt exhaust.
because we couldn't get it higher than 160hp. and most abarth 595 with IHI turbo push 170 with out the uprated intercooler and such.
so i think there is still power left on the table.....
anyways it drives great and was a worth while. cruise control still needs some tuning but works fine for now.
yesterday i went for a cruise
avg fuel consumption at the pump: 13,5 km per L or 38.17 UK mpg
with all that fun under the bonnet, the brakes are up to big task and are really too small for this. but thats for an other time, just like electric hydraulic power steering....
