If you are not planning any major mods like a cam,heads,etc. dont worry about the diablo,just get you a 3815. Isold my friend my 3815 for his 05 durango and he said he could not drive with out it any more. 91 octane mode set it and forget it.

 

It plugs into the OBDII port under your dash. Then you go through the menu and select the tune you want. It downloads and saves the factory tune, then flashes the computer and loads then selected performance tune. It is very simple and only takes about 10 minutes or so the first time (first time takes longer because it downloads the stock tune)

 

I just noticed that the 9r09 crom has a new date next to it, was 10-5-10, now it says 1-10-2011. Anybody updated to see what is different? It doesn't say anything different, just a newer date. Not sure if it's worth going out in single digit weather to reload the stock tune and update or not.

 

Havent really checked it out anymore since Im custom tuned now with my cam, have you checked the forums to see if there was an addition or a fix

 

Not yet, i will though.

 

I have an 05 Ram 1500 Hemi. I'm currently getting like 13mpg. Which of these tuners will best help me with fuel economy? I currently only have a custom dual exhaust on my truck. I'll be putting a CAI/Ramair on it soon. Right now I just primarily want some better mileage. Any performance is extra bonus.

 

I doubt if any tuner is going to satisfy you as far as MPG go. The best I've seen is maybe 2 MPG hyway, at best, but the overall drivability is much improved.

 

At 13mpg you are about average with the rest of us. Join the club and realize thats just how it is.....

 

I picked up about 1mpg with the sc 91 tune and about 1.5-2mpg with the diablo 91 tune. No tuned alone will give you excellent mpg

 

How 'bout if I swap my top end over to an MDS system? lol
