Ok i go to 0.55 bar of boost now and new R888 tyres. I have race on sunday on 201m and run belive or not 8.9s. I beat a lot of cars like new 4x4 impreza sti, VR6 supercharger, Honda supercharger, dodge stealth biturbo, fiat tipo 3.0 V6 turbo with alfa engine... Its amazing that engine is still with stock pistons and rods... Its seems like i do proper tuning and im realy hapy.

One movie of race...
