I would like to get a little more power too. I think I'd REALLY like a tow/haul mode for the tranny to make it hold shift points longer. I too live in the mountains and usually just leave it in 3 to keep the tranny from hunting.
So:
1. Exhaust mods help. Does eliminating the resonator? How bad is the drone without the resonator?
2. The K&N intake helps. How much? Does it affect water fording?
3. Has anyone tried a chip? Is there one available? How's it help hp and mileage?
4. Any specifics on the throttle body mods? </div></BLOCKQUOTE>
1) I don't know how the stock exhaust sounds without the resonator. I have the B&B/SMA (no resonantor) and the sound isn't that bad. Deeper but no V8 sound. B&B told me they measured a 8 wheel HP increase with their exhaust on a stock H3. This gain seems typical.
2) I think WhiteH3 posted some of his dynos done by K&N on his H3. I think the gain was over 15 hp at the wheels. I have the Airaid (the price was right) with my own pipe that bypasses the intake resonator. The K&N system seems pretty good. I can't answer the water fording, but my guess is that not much different. The filter element may be exposed to more splashing than stock. The stock system breaths from the passinger fender. With the Airaid system, the metal bracket can be removed and the stock lid put back on in about 1 minute for off-roading. Teh K&N and Airaid system will produce more noise.
3) NO chips - programmers are in works to reflash the PCM. I haven't seen any out yet.
4) The throttle body needs some cleanup. You'll need a die grinder or a dremel to reshape the TB input and output. The input needs some slight-medium reshaping. The output needs more work. Some people knife edge the throttle blade too.
