Default Raising redline?

I was just wondering how easy it is to raise redline on these cars and if it would be really worth it. I have a 2000 mustang GT. Its got full bolt ons (intake, LT's, exhaust etc.), Crower stage II N/A hi lift cams and patriot stage 2 heads with full crower valvetrain. It also has forged pistons, rods, etc. I have the dyno chart on it and the car is making peak HP at about 5500 RPM's and slowly falls off after that. The car is making its peak torque between 3k and 5k RPM's. The peak HP is about 280 wheel and the peak torque is 310. I was wondering how quickly the power falls off after these peak ranges and if I would benefit from raising the redline say 500 or so RPM's? I can post a picture of the dyno if you all would like to see the curves.

Thanks in advance.

Default RE: Raising redline?

Post the dyno chart and I'll give you my $0.02 worth...[/align][/align] [/align][/align]In 1st gear my lightly modded '03 GT (with 3.73s) would bang the rev limiter before you ever though it would happen while driving (I.e. while still pulling strong). I upped the rev-limiter to 6700 rpm (+500) and still bang the limiter every now and then in heat of battle.[/align][/align]In 2nd it's not as pronounced, but I have hit the ceiling on occasion...[/align][/align]As for easy, it's a piece of cake if you've got a tuner that can do itI assume that with your mods you have a tuner?[/align][/align]
