maybe some tuning would help you .. We have gained both ET and MPH on every car we have done .. Melissa was running 132+ unlocked LOCKED UP THE CONVERTER AND HAD A BEST TODAY OF 138.57 hmmmm lemme take my shoe's off to add that up...ummm thats 6MPH according to my toe count:biggrin: I believe there is more left in her car but she got kicked out :redface:
