i've never seen any car that doesnt benefit from a good tune, and hondata is a pretty damn good sysytem
hondata imo is always a good mod.... i've seen gsr's with just intake and hondata gain 20hp with a good tune.
if you add more mods down the line and have it re-tuned it will give you peak performance from those parts as well.
i can tell you for sure that you WILL get gains from hondata, it will maximize your current motor's potential.
what i cant tell you is exactly how much you'll gain from it right away.
if you do cams then have hondata tuned you wont be dissapointed
I think the best way to optimize the shift point for the auto is with an ECU chip....but the Hondata can help with fuel management problems and rid yourself of the redline (use with caution) lol
Absolutley, like Todd said, even a car with just bolt-on's can benefit from a retuned ECU. And Hondata is arguably the best ECU tuning system you can get. It's not cheap, but you get what you pay for with Hondata, as with anything. There's not much it can't do.
