Re: H3 Engine Performance Up-grades
With what I did in my sig, I noticed a nice improvement (prior to the 35" tires). The K&N without the resonator is quite loud, especially over 4k rpm's, and that's where you notice the power the most with my setup. Not to usefull for the trail, but nice on the highway. I had a Jet chip on a previous truck and didn't think it did anything. I wouldn't spend money on one of their products again.

Re: H3 Engine Performance Up-grades
With all due respect to the GM mark of excellence there are some things we mortals can do to enhance performance...
Hoping there are some Thomas Edison types out there to solve this oil mess we are in lets not close our eyes to even marginal ways to improve what we've got. Just like we wish we had better lungs for ourselves...
Enhanced respiration for the engine cant hurt...
There are some cold air intake mods that are out there for do it yourselves (do a google search) or for the lazy rich folks to buy from the usual suspects for over time will save you your investment dollars. Especially while fuel prices are rising.
On the back end there are header type exhaust systems to help folks that are listening to the mantra of a clean colon is the secret to long life... There is Magna Flo and other manufactures of oversize and over sounding exhaust systems for the rear end crew.
In the middle of the road there is the chip crowd that favors the electronic approach to saving the H3. Here we second guess the genius at GM to prove our equation is better than Poindexter's and spend $500.00 to some marketer who has better mpg religion than thou...
In summary go to the Home depot buy some black pipe and glue cut some holes in your intake manifold and hope for the best. Its a free country and your warren tee guy will surly not care that you have no concern for the structural integrity for his masters design

Re: H3 Engine Performance Up-grades
Sorry for bumping this old thread up. For once second I thought the OP was talking about the cheap chips they sell on Ebay. Don't waste your money on these. I was thinking about getting a performance chip too, but it looks like these things don't do crap. I was reading this performance chip article about it, and it looks like these things don't work at all |

Tandrew,
Thanks for that. Can you be more specific about the advantages of PCM. They claim 1-3 more mpg and 8-10 hp improvements...
