You are right there as so many others have been. I went backwards adding the drag radials in. Hopefully you will go the other way. That was with the roadster. We have changed a few things since then with the roadster. Just haven't been back for new times. But, you are now in a club of low 12 second cars that are just at that hump you need to get over.
I am still holding the coupe back until everything is finished. It is a track thing. The guys at the track protested the roadster so I can only test and tune with it. Once I know the coupe is ready, I will show up with it and have some pay back....lol.
