2. Is an HV3 worth it? Is it more for top end or low end? IS it hard to install?

3. How much horsepower would i expect to get from the following: CAI, 180 degree thermostat and a HV3? ( I know it wont be a ton, but I have a budget)

THanks
Its not a big deal if you bought a CAI or build one yourself. Its a matter of personal preferance. As far as the 180 tstat it will work without a reprogrammed pcm. I ran one for awhile and I did not notice much. Its up to you if you want to do it. The HV3 is definitely worth it. You will notice it. Pairing it with a set of rockers will make it even more noticeable. Don't expect to much HP from the items you listed.
