I tuned another gt with a s4 blower here is the before and after we added a chicane pulley 42lb injectors mass air and throttle body and fuel pump. The first run had fuel upgrades including lightning 90mm mass air but minus the pulley. Keep in mind that on the street the car will be about half of a point richer. The last run was with the motor cooled down. With the motor warm it will be a hair richer. By all means this car is safe. Cool weather and less humidity and a little race gas this car will be easily knocking on the 400hp door. This car made a hair more power then my 00gt that ran 11.9 at 114.8 with stock exhaust but its a vert so we shall see what it does. oneqkgt@aol.com for info on getting these saleens running. oh af was at 11.5
