Default any clues?

I recently switched out my LS1 to an LS6 IM. I also changed the injectors and cat back system.

With those changes I lost 4-5 mpg. Anyone got an idea why?

I am lost, please help.

Thanks guys.

What injectors did you change to? If they're not the stock flow rate you will have to have it tuned for them to work properly.

Are the injectors new? Could they be leaking?

The Woodlands.............man I wish I was back there. I am from Houston and wouldn't have any of these issues if I was back there. I think the tune is the problem. I am going to contact a guy in my area and see if he can get me in. I am sure they aren't leaking. I was basically looking for affirmation that it could be the tune.
