Alex, I like modest power and not temper with the ECU. I have had bad experience with my previous vehicle about massive power. I replaced the engine three times
SuperWhite, perhaps the I/H/E would only add less than 30hp but the price for those that you listed is way too much?? Am I the only one that is paying less for my mods? I do have buddies here that owns and operate a "Pimp My Ride" kind of store. I can get those parts about $600 and I'll install them myself. The paint job that I have on my car would run about $5,000 to $7,000 but I merely paid 10% of it.
Supercharger sounds nice but the dealer here charges $4,000 for it. Although with the I/H/E it might not be half the horsepower you get with the supercharger but sure beats the price! The price I can get the I/H/E from my buddies is about 15% of the supercharge's cost.
What other mods do you guys know of to add hp without reprogramming the ECU?
