Hello we are new here to the forum but anxious to get posting as we love our Tahoe and also want to learn from others about the path to great/proven mods.
The only thing we are unhappy with thus far is its fuel economy. We are getting 13-14 mpg in town and havent had a good road trip yet to confirm accurate highway mpg. I realize it will do better in that area. From my background in motorsports I can only assume the first step to help the fuel economy would be a cold air intake? Aftermarket exhaust? As I have EFI live tuning software for my Duramax Diesel pickup I assumed a custom tune would help. However after looking into it the tuners I spoke with could only garuntee 1 mpg improvement with a custom ECM tune. After the cost of a vin liscense needed for uploading an EFI tune and the cost for the tune itself it didnt seem to be worth the investment. Maybe long term? Some have suggested an Edge tuner? Any input from you guys is much apprecitated. I realize its an SUV and not a prius im just looking for as good an improvement as I can get. Thanks in advance!
