Hey guys i jus bought a 08 gt/cs, it already had this mods on it 4.10, air filter 90mm mas air, shorty headers, h pipe with ford racing mufflers, hurst shifter, and sct from brenspeed. But every time i punch on it i have to shift in 6500 but i feel that its needs more rpms something like 6800. Thats how i feel it the gears are to close. Any suggestions, how much its ya red line on tune cars.
