Default Diablosport
Well, I got my Diablosport Predator last night, loaded it up and all I can say is WOW. Night and day difference. Going to straight pipe my stock exhaust for now to help with the EGT's. Just filled her up and going to light foot it for the next few tanks, which I do most of the time anyway, and see what kind of mileage increases I can see. I've been averaging 17mpg with 3/4 daily driving and 1/4 towing. I commute to work 33 miles one way and have been setting the cruise at 65. Hoping to maybe see 20mpg.

I don't see any reason why you shouldn't. What setting do you have it on?

youll have that.

You should see 20s with a light foot. I pound on mine with a huge smokey tune and get 15 w/35" tires.

I set it to the 65HP setting. Looking good so far.

After this tank give the 85HP setting a shot. Most see the best gain with that. Be easy with the right foot is the key thing.

Just make sure you get that larger exhaust installed first...

I also this weekend put in a Diablosport Predator tune. I am running the 85 HP tune . All I can say is nice. I have about the same commute an lots of fuel milage data so I will chime back in later this week on my findings.

I picked up a wopping 1 MPG gain. Not exactly what I was looking for but the extra power sure is nice to have when you lay the hammer down.
