flubyux2;917293 said:wardog, how did you only get to 105mph on the wheel speed if 4th gear is supposed to go to about 120ish? do you have short gears or something?
your torque looks fairly strong. not bad at all for only 11-12psi. you should be able to pull out low 400's closer to 20psi... or at least near the 400hp mark.
the 440's should be able to do more before they max out, but you have to remember you are still on the stock ECU. unless you have an FCD, youll have a really hard time getting the full potential out of your stock fuel system.
