Fully developed Colorado/Canyon tuning options
If any customers have pre and post tuning fuel economy and wish to post it here, that would be awesome.
Even if you are using your truck in an off-road application, GDE will not sell you any of their tunes. It is rediculus...Wow, I lost 6 mpg with my lift and tires. How can I tune in California... this state blows.
I don’t think “they” (CA smog techs) can actually see the GDE tune. I think they are just looking for ready codes on all the emissions equipment when they plug in. Plus a visual inspection of the engine. As long as you don’t have any visible mods or a catch can you should pass smog.Thanks, I just created a thread about a tune for California also. What kind of tune? I don't want to have to revert it to pass smog in 2 years.
