Not that those mods help at low RPMs, but anything to help make an engine breathe better is not bad. I just would not waste the money on a chip. Chips, IMO, are only worth buying for diesels, where they can give you 100-200 extra lbs of torque at the low end. But even then you have to have the right complimenting parts or the engine will be starved of fuel, or air.

Gun it and run it!
