Okay, hopefully I don't come across as too stupid but I have a couple of questions. I am ordering a Kenne Bell next week for my 06 Stage 1 Roush Mustang. Getting the non-intercooled 5psi kit. They say they send the tune and you don't have to get it custom tuned. Is this true? My mods are JLT CAI, SCT tune, and 4.10 gears. With the Kenne Bell will my JLT and tuner be useless and can Kenne Bell send me the supercharger tune adj for my 4.10 gears? Thanks in advance!
