are you sure? i emailed them several months ago and they told me they werent going to invest time into the transmission stuff because it was already out of date. then SC came out with theres and its been all good.
is DSP going to do the 04-05, and 06 ones along with the 07-08? they all have differant systems. im waiting till SC comes out with the 06 stuff till i buy one.

Is DSP actually going to do trans tuning for us older 3rd gens? They have removed it as "coming soon" for the 04's and 03's on their webpage and now it says nothing at all about trans tuning coming for those two years.

yea, but the 03 has that wire you can cut or pull and it disables the TMR which is the same as the later versions with the more up-to-date ECM system. so they cant tune it a whole lot like the later versions that have TM and are limited on what they do my the computer.

yep, that would be a sweet tuner, but im sure the SC engineers arent going to let that happen very easily.
I always though it would be great to sell a cable to be able to plug in a laptop to the truck port and have the tuning software on the laptop to tune and change things with. I would personally prefer that as to updating the tuner all the time and then going to the truck to update that.

the cortex has a 2 year warranty for your vehicle with it so theres no reason NOT to get it. the flashpaq and cortex are the exact same except for the warranty.
the XS is just that. for better MPG's. since you have an 08 get the 3865(flashpaq) or the 3950(cortex) and youll have tranny control also. that will also help you get better mileage.

I bought the 3865 for my '03 4.7L and it doesn't do transmission and *maybe* 18HP (generously) gain. Although I felt a little more "omph," I ended up returning it as it didn't seem worth it to me. Not really much you can do to the 4.7 without getting into mechanics. I used the money towards gears instead and noticed more improvement in city driving mileage and get up and go than I ever did with the superchips.
