I added a boost line to my regulator tonight so that I can back off the low end fuel delivery and still keep my top end where I need it. This regulator has a 1 to1 ratio so for every pound of boost my pressure will go up 1 pound. I will be at the track tomorrow to see how it works. I also put a set of Nitto 315 35 17's on today so I am hoping to get some great launches. They sure look good it is a lot of meat under that car.
