Guys with the 300 tune

[jac97psd]

I have heard nothing but great thing about this tune, but just wondering has anyone notice any mpg gains from the lower tunes? I really want this tune but coming up with a extra 400 dollars is a little hard right now. Thanks for any info.

I wouldn't waste 400 dollars on it IMO, ya it's a good tune, but not worth the money, I drove it for a little while then went back to the 310

So you think just spend the 300 for the 275 & 310 tune huh? What did you not like about it or were you just used to the 310 tune? I heard it makes almost the exact same amount of power as the 310 but shifts a lot smoother. But I was really concern what mpg improvement will I see over the 250 tune.

$400 gets you the 275, 300, 310, and all of the EGR delete tunes.

You'll see a SLIGHT mpg increase with the 310 over the 250, if your after mileage I would stick with what you have, because it's going to take a long time to recoop that money in fuel savings. If you want to have fun and go to the strip and stuff and have one of the quickest diesels in town, spend the money and get the race tunes from either spartan or KEM.

Well I would get is the 275, 300, 310 tune cause my other tunes already came with the EGR delete.

Beating sports cars in a 8k plus pound truck is always fun. And I am a speed junkie which is not always a good thing.

im just waiting for them to finish up the job 1 files. but IMO, i would say go for it! there wont be a dramatic increase in fuel mileage, but that tune is just too much fun. i love finding a guy around here that thinks he has the fast cummins around and then whoopin up on him. theres nothing like it.

Yeah I agree. Next week I will be buying the 275,300,310 tune plus a downpipe and CAC piping. Can't wait till everything will come in. Getting everything from Rudy diesel performance. So anyone in the DFW want to help out a fellow member with the downpipe.

I installed the 300 tune and the TCM on Saturday and love it so far. I have been running the 275 dd for about 20000 miles and my mpg went from 11 to 17 mpg on my F350 dually, I don't know any milage on the 300 but I love the shifting, and the power got a lot better after changing out the stock wheels and tires I had lost a little power due to the bigger wheels and tires but the 300 helped a lot.
