Personally, I think this IRS business is bullshit. I've seen a LOT of dyno runs and have never witnessed much of a difference between the two cars (F vs. Y bodies). I've also owned both a 1999 Camaro SS and a 2000 Corvette. The 'Vette was about equal to the SS both on the dyno and at the drag strip when bone-stock. The only real difference I noted was that the C5 was a stronger top-end car when stock than the SS was and that it took to mods better and got faster at a quicker pace than the SS did with the same or similar mods. I attribute this to weight and aerodynamics.
If you go to a Corvette Challenge drag meet sometime you'll see that the C5's IRS doesn't seem to be handicapping any of the cars there. Also, keep in mind that the 'Vettes that once terrorized the streets in the '60's were also equipped with IRS and it didn't seem to hurt them much either.

F and Y bodies both have TM. ALot of people didin't know F-bodies did, hell, I didn't know until a couple of months ago.

i mean is it in the tune, that they get from the factory and if thats true, than why would GM do this to C5's?

Competitive driving mode was present right from the very start...TM in the six speeds is basically the Torque limit value that is present in the torque management segment of the programming...It does not pull timing at shifts, like the auto's do, but the if the PCM calculates that the engine is making more torque than the factory programmed value, it will pull timing until it's calculation is safely below the set point...
