Like I said earlier, I want to buy a tuner. At first I was looking at the SCT. Then read some on the Diablo. Which is better? They cost about the same.

Are there any tuners for the 3.9L? How much HP can you gain from one of these "plug-in" tuners?
Not sure. I read from 15-20 RWHP, but it's not just the HP. With the tuner you can adjust shift points, raise the DAMN speed limiter, adjust the speedo for bigger/smaller(yuck) tire sizes, and a lot more. I haven't seen one for the 04V6 yet. All the ones I see are for up to 2003 V6's and V8's.[sm=gears.gif][sm=gears.gif][sm=icon_rock.gif]
