I have a 03 hummer h2 with longtube headers and free flowing exhaust. Just recently installed edge cts2 programmer. Was thinking of installing jet performance throttle body. Anybody have any experience with them, and know if they work together with the programmer. Thanks

 

No experience with them but with most all performance mods the basic tuners pre-made tunes are setup to improve a stock setup and will not give any additional benefit to the headers (or a cam and most other hard performance mods). You need to have a custom tune done to really get the most out of anything beyond stock as the custom tune will be able to compensate and take advantage of the modifications. Basic canned tunes are generally pretty good but air, fuel, volumetric efficiency ratios, etc all are set to optimise the stock components and as such cannot properly take advantage of the freer flowing exhaust, etc.

 

i have it on my H2 paired with Granatelli Motorsports 350120-C tuned Mass Airflow Sensor and i can truly feel the power of the 6.0. Having said this, i also have the "Air Doc" and "Custom DiabLew Tune" with "long headers" and full "MagnaFlow" exhaust system,

So i'm certain that the performance gains i have is a blend of all the above.

 

very nice rig you have there. Looks fantastic, usually I don’t care for replacement wheels but yours fit the look perfectly!

 

Thank you sir
