289rwhp (assuming SAE) is a solid number. What did the air/fuel ratio look like? Can you post a graph of your dynosheet? That would help out a great deal.

A bone stock '01 should theoretically dyno 272rwhp, give or take a few hp (factor in 15% for drivetrain losses, so 320flywheel hp * .85 = 272).

If you feel your number is slightly on the "low" side, there could be a few reasons. Perhaps your air filter is dirty (read: restrictive), sparkplugs need to be changed (read: worn), or the tune is not "ideal."

Just some ideas...

Mine with long tubes - cats - puleys - cai - and chip is sitting at 315/316. That is with a colder plug too.

I understand mine is on the strong side but you should be closer to 300 for sure with your mods.

Kind of low, yes. Get some headers and gears if you don't already have them. Then dump the diablo and get a custom chip and tune.

Why not get just get a custom tune and use the Predator to upload it via the Predator??? Much easier and cheaper in the long run....
