    I'm not the expert and I make no claims for other years or submodels.
    my car (02 Z28) came with 245/50ZR16 Goodyear Eagle GS-C tires.
    paid $225 extra as a option. still have my order sheet and window sticker.
    if its speed limited, its after 155.

    You should know

    ALL THREE OF THEM WERE SPEED LIMITED.

    YES.

    EVERY F-BODY IS SPEED LIMITED UNTIL PROGRAMMED.

    The Z-rated rubber cars get a 160 MPH limiter, perhaps that's why you don't think that there is one. There is an intermediate limiter on some cars at like 125MPH and verts only get to 112 (or 116 I forget) before the limiter.

    I've had two of the three of the LS1 cars I've owned to at least 135mph and both of them were still pulling hard. And all three of them came with the Eagle RS-A tires. My first two were new cars and the one I have now, I bought used. And I didn't need either of them programmed to accomplish this.

    All of the cars are OEM limited to 160 at most, 135 (or 125... I don't look at them anymore, just set to 256) for many, and 112 for a few.

    You're right. All three of mine were set at the 160 limit. At least I know for a fact, two of those three were and are.

    I just looked at the sticker on the inside of my drivers side door and it lists my front and rear tires as P245/50ZR16 and my car's a Z28 with 2:73 gears. It's never had a speed limiter.

    That wasn't really for you, Frost. I believe someone else had said all LS1s that were 2:73 geared, came with the non z-rated tires and were governed at about 130mph.
