Was able to read the computer of my C6 yesterday. Might be the first read done. Was helped by the good folks that make the EASE software and John Rovner.
Took the laptop and did a run last night up to 130.
I think the big thing we took away from the test was that bolt-ons for the C6 won't give ya much until you can flash the computer. That software is not available now.
I guess the question would be "when" will an LS2Edit be avaliable?
Your guess is as good as mine on that one.
Some of the graphs of the run are posted on another forum.

THANK YOU!!! That shows a lot of what some have speculated about on this board. When GM announced how much torque was available over such a huge portion of the rpm range, it seemed very likely timing was used to reduce the know behavior the 2001 LS6 cam. Your timing is very low compared to the LS1/LS6 calibrations. It will be very interesting to see what numbers a stock LS2 makes when a good tuner has a chance to just optimize the PCM calibration.

Right now Water Injection looks like it might be a good option where a tune won't be needed and some hp can be gained.
The "bolt-ons" don't look like they will give ya much of anything, and maybe even a loss.

So you're saying that an intake and longtube headers won't give me the performance increase until I get an edit. I thought others have seen nice gains with these two mods on their C6. I'm new on these performance upgrades so trying to get as much info as possible. Thanks.

Do what you please but I'm waiting for the ability to flash the LS2 computer.
Water Injection will be the only add-on I will use for the present time.
