Will a programer and exhaust really help my MPG's that much?

[05_F250FX4_6.0]

I am wanting to get a mini maxx programer and a flo pro exhaust for my 2010 6.4.
My question is spending the 1300 bucks worth the MPG's I will gain? Will I even gain that many MPG's? Also, how does the flo pro exhaust sound? I am looking at the 4" one from the down pipe back. I don't want it to be too loud. Thanks for any info.

I'm going with the XRT and 5" DP back Diamond Eye with an S&B intake. Curious to see what responses you get as well.

From other guys here it seems that running on the hottest tune with a schedule 2 tranny will get you the best mileage, as long as you can keep your right foot off the pedal. I baby mine and intend to do so once I delete/tune.

Depends on your truck, how you drive and where you drive....that being said I'll say no it won't.

Thanks Debbie Downer... I'm kidding. This is very true. It can extend the longevity of your engine life though.

Have you not seen improvements in MPG?

[Clayton1985]

Just being honest! Not a huge gain...maybe a couple mpg on highway.

I really don't know that much about diesel trucks. But it seems to me that everywhere I read, people are saying if you get a programmer and an exhaust your MPG's will increase. Why do people do this if it doesn't help out?

You won't see huge gains with a tuner and delete, but you thrown in a EGR delete and you have added life to your engine.

my mileage went up like 2mpg but it runs like a whole new truck! u will be impressed with the power but dont get your hopes up on a huge mpg gain

I don't know about other people but with my lift and tires I was getting 11 bone stock if I drove it easy. I got a mini max and just the delete pipe and I'm curently geting 14 driving it hard. I drove it easy for a day and was getting 16. I know that's off the lie o meter but I drive the same distance everyday and have gotten 2 more days and aproxemetly 80 more miles out of a tank. The hp gain was worth it to me though.

I did it more the the engine's well being, and the power/turbo lag more than the mpg. Town driving not really any diff, highway gained a couple mpg's (hand calc'd, not the useless lom)
