Well I have been itching to run the Diablo sport on Extreme and wanted to see if I can get better mileage that way. Turns out two things, I put my foot in it a lot more, saw a lot more smoke and got worst mileage. I am going to try two mode next and see.

 

In my best "Rainman" voice.... yeah... smoke way too much smoke... yeah smoke!
Some guys are reporting better mileage on extreme, while others claim better on tow mode, while most see the best on economy/performance. I have just been testing out "tow" mode, so far mileage isabout the same as ecno/perf. with tranny temps running higher on tow the ecno/perf? Can't figure that out!? Although boost runs lower as well as theEGTs a little lower on tow. Thinking of looking at the new Quad addrenaline which, ought to be out soon, still beta testing. So far it looks very promising.

 

I saw my best mileage on performance/economy. but the MPG increase wasnt that great. the more black smoke the more fuel that is getting wasted. I saw twice the mileage with any of thw quad boxes I've ran.
but the predator definitly made the most power and smoke

 

I love the power this thing has. and I am not going to cry over a couple miles per gallon, Ido have a big truck and did not buy the truck as a economy car. I have the mini van for that. I am just testing the difference and noticed it is a big difference. I have ran it on performace/economy setting since I have had it and it has great power and decent mileage. maybe when I stack it with the power puck it will help mileage[sm=confused06.gif]... Or maybe just a crapload more power. either way it is bound to happen.
