I'm talking to a local shop about having my truck deleted and tuned with the MM3 tuner. I asked the question about fuel economy increase. The shop owner said I should expect 3-5 mpg. Being I average about 12, that's not bad. My truck is my daily driver and used to pull my 38' 5th wheel.

I have heard and read that doing this work for economy is a waste of money. My experiences with other type vehicles have been most claims are greatly exaggerated.

What is the real scoop on this? As you guys know, it ain't cheap!

thanks
