Anyone using Jet Stage 1 Module or found a performance programmer for the H3. Now that I have 35's I would like to tune the performance. Thanks for your help!

 

There a lot of folks using the Jet programmer, and a lot of folks using the PCM4less pcm tune. The PCM tune will give more hp/economy, as it is rather advanced tuning. Only downside is it MAY void your warranty depending on the dealership. The JET chip will still give more hp, but not as much as the custom tuning. Plus the PCM4less tuning can tune for your 35's to correct the speedo. The JET chip can be removed during trips to the dealership.

 

It really depends on what you are looking for with regard to a programmer. Are you looking for software to do it yourself or are you looking for a someone to hook up your car and do it for you?

Someone who knows what they are doing will blow any chip or canned program out of the water all day long..

Having just gotten into the Hummer scene, I'm not sure what all is available out there but the "box tunes", while better than stock can be pretty rough in other makes of vehicles.. Settings that will work well for 1 car may not work well for another car and so on..

If you want to get the absolute most of your Hummer, take it to you local dyno shop and tell them what you want..
