Hummer H3 For the Hummer driver who wants the rugged look and off road capabilities of the Hummer, but in a smaller size and with a more fuel economy friendly engine.

What should I do to add more horse power to speed it up?

Buy an H3 Alpha, not speedy but better than the I5.

You bought an H3 and you want to go fast? Ever dawn on you H3s are FT 4X4 Off Road Vehicles designed to navigate off road obstacles at low speed, not to be speedy on pavement?

Anyways, pretty close to this order:
Intake;
Efan conversion;
PCM Tune;
Throttle Body Port Polish; and
Cat Back exhaust.

Do that and you will be about as fast as an H3 can be, until you buy and Alpha and do the same things to it.
