Which programer should I buy
I have a stock 04 h2 and I'm looking for better throttle response and better mpg.. I've done a search here and noticed most posts were very old, and new stuff comes out yearly, so tell what your running and if your happy..
Thanks,

those should get you pretty much where you need to go. they are pretty recent from the past 8 months or so.
most will tell you a custom tune is the way to go, and it is the best way to get something from your h2.
im happy with my superchip cortex, it does what i want it to do and gives a bit of improvement with the mods i have.

The hypertech sounds great but they don't advertise better fuel mileage. I'm looking for better mpg and hp too.. A friend of mine runs diablo predator and went from 10.5 to 14 on the highway. I wouldn't of believed it if I didn't see it myself. Can hypertech offer the same??
