Diablosport Forums

I have an 05 Cummins, and I just installed the Extreme PP (P1010). Aside from having to resolder one of the connections to get it to work, everything seems to be working well. I did notice that my MPG gauge goes crazy stopping only at 99.9 MPGs, though. I wish right!

Anyway, my question is what "setting" should I turn the dial to in order to enjoy the best fuel economy with this, and what kind of MPG increase have people seen with this? I'm pretty much only concerned with fuel economy. Any information or feedback on experiences with this product would be appreciated. Thanks! -Jon

to be honest, you'll want to try it at a few different settings for a few tanks of fuel to see where you get the best gains based on your driving style...

Thanks

Yeah, I'll have to do that. I just realized that the 2nd setting on the Predator is supposed to be the most efficient so I'm going to try it first. That is actually supposed to be the most efficient setting out of everything that Diablosport offers, correct? If I'm mistaken please let me know. Thanks for the prompt reply!

im thinking about buying the extreme pp but i have never seen the "dial" to one. do mind puting a pic up of the dial where you change the power setting or anyone else that has a pic of one. it would be going in a 04 CTD
