Predator Diablo or Hypertech - what can I expect?

[flyboynm]

I live at 7200 feet above sea level and have been thinking about getting an engine programmer. Which would be best to get? I know that depends on the person, but I just am curious what people say. Also, here is the kicker...if I get one of these items, what can I expect in performance increase? I have a stock 02 Avalanche, 5.3 liter, and have only added a K&N Air filter to it. What kind of horsepower do I get at this altitude? What kind of horsepower increase do you think I could get out of the engine computer mods? What kind of horsepower increase do you think I got from the K&N air filter? Finally, what kind of increase can I get in gas mileage can I get, if any?

I have both and I would say the Diablo is far superior. It reads codes and is a lot more adjustable than the hypertech. I cant answer about your horsepower at that level. You wont see much measurable HP just from a filter. A FIPK full intake tube system you may see a few. Increase in gas milage is not much different with just a filter.

Wanna buy my Hypertech?

Hope this helps.
