Best MPG and other questions

[NYMustang50]

OK I have the U7130 with the latest update on it 9r07 and my truck is a 03 Dodge Ram.

Whats the best tune for MPG like the best one out of the Predator. Also what do these mean

Extreme puff tune
Extreme RKL tune
Extreme RKL puff tune
Extreme RKL puff tune w/ no timing added

I know the RKL means Road Kill Larry but whats the puff mean and also out of these and the factory tunes whats the best for MPG?

You may have to do some experimenting to find which tune gives you the best mileage based on your driving style.

The rkl tunes are custom 200 HP tunes that you can download, puff means it will emit a large puff of smoke when you get on it.

OK I installed the Extreme RKL tune and downloaded 12xxx_ext_puff_toons.drd because my cal number was 123xxxx. So I went and did all that and put the tune of Extreme RKL on my truck started up fine.. Drove down block and heard a lot of timing rattle and felt a lot of surging.. Whats the deal? why? so I went back and quickly changed it back to the factory predator tune of Extreme and now runs fine like it did... Did I download the right file? I have the Release 9r07 do I need For pre 8r28 revision or For post 8r28 revision because I did post..

Those are HOT tunes, if you or the truck dont like them, it may be best to stick with the canned tunes...
