what i envy about you srt8 guys (besides the $/hp) is the way the aftermarket community really stepped up in such a short amount of time. we've got 3+ years on you guys and still don't have an adjustable tune like your diable/predator. for the most part we have to send our ecu's off to someone and hope they guess right! 
Our SRT's are in pretty good shape, may get TCM support soon through Diablo.
A company has just come up with TCM reprogramming for the SRT's, which is huge.
Imagine if you could change your:
*TCM Torque management
*Rev Limit
*Stall Speed
*Line Pressures
*Clutch on/off apply variables
*TCM adaptive memories
*Modified Shift Schedule
The SRT's use a Mercedes TCM (Siemens)....I wonder if it is the same one, only programmed different.
Obviously, this would only apply to the NAG1 5 speed Mercedes vehicles if at all.

They do make a lot of parts for the hemis, which is nice. But, the weakest link on the SRT's is the "half-shafts". With a good launch, they can easily snap. There are aftermarket axles by DSS, good for 1000hp, but they're around $3k.
I don't have any type of exhaust, or headers. Just an intake, stage one heads/cam, and a good dyno tune. I have the power, I just need to work on the traction. I'm running the Vredesteins, and haven't been to the track with them, but as you can see in the video -- they launch pretty darn well. I can't wait for Moroso to open in October! Thanks for the comments guys

Headers in the SRT-8's need tuning to see an increase in hp.
I started with a stock 6.1 cam in my 426 and changed to the 268....big difference without a sacrifice in fuel economy.
The hood has hardly been opened on my SL in the past 11 years and I probably won't mod the next MB either.
