Well boys, now I know..
As stated before I had no chance to get a dyno reading. However last weekend I did my first track event with the newly mapped engine (And my new Hartech race sump, can tell all about that later)
I can confirm that for the first time I was totally even with the 996/997 carreras on the main straight. I also shared car with my father who ran in another class, he noted that the car defenitely had more power than at previous events.
How much extra? Wish I knew, but itīs significant.
