So after upgrading to Stage 4 I wanted to try this again. At high revs it is a little faster than at Stage 3. However, I have the notion it doesn't match 315hp. Certainly, the new tires have more grip but I doubt it makes a difference of up to 40hp at 6500rpm. Tire pressure is 2.8bar/40psi. Any ideas are very welcome! :)
