Superchips updated tune

Has anyone updated their SC tuner with latest tune? I did mine and lost my great gas mileage, not sure if that is the cause of it or not, the only other thing I did on mine was changing my oil to Synthetic. My wife and I took our daughter to Disneyland/Knott's Berry Farm, on my way there I was not seeing 22 plus gas mileage that I was getting so I stop and adjusted my tune and same thing so decided to go back to stock tune.....then I started to see that great MDS gas mileage....I got 23 plus on my way there (using cruise control). I left stock tune all the way back home not feeling like wasting gas, these Hemi trucks don't lack power passing trucks/cars so I was happy to leave it in stock tune. I have change it back to 87 updated tune since I like the 1-2 shift point and 2-3 shift point....I am checking with DCT, maybe they can tell me something about why I lost my great gas mileage.

Anyone has any idea?

Just a thought; could they have altered the A/F ratio so that the truck is running richer in the the lower RPM's?

I know that DS tuner I'm waiting on will supposedly allow those kind of adjustments.

Like I said just a thought. Whatever you do I hope the truck runs good cause I sure wouldn't want to meet you in a Toyota.

Thank you Hemi317, I love my truck too much to get rid of it.....Toyota thing was a joke

I am really hoping to hear from DCT on this, I am not sure why I lost so much and from what I know these updated tunes are for shifting later than normal settings so when I am on the Freeway it should not matter, these settings are not even in use (so to speak), especially using cruise control keeping steady speed of (depending where) 55/65/75....I think I also remember DCT said it takes few hundred miles to get the settings working correctly but I don't think that is in my case....anyhow hope to hear some good news from DCT soon.

I think DCT is on vacation, no words from them so far....that alright, they need their break too. Gas prices are dropping so I may switch back to 91 tune....I like the way my truck perform with 91 tune. Every traffic light when I barely step on the gas paddle front end jumps...I like that feeling. It does now but not as much like 91 tune, not to mention how the truck roar when I nail it.
