What are the differences in these tables? I have only seen a few stock tables posted from a stock C6 Z06 and they appear to be the same as the base C6. I am also curious if the top speed limit is increased on the Z06.

Getting ready to try for my BBG run and wondering if I should change the top speed value.

As seen below the torque values are the same for all C6s (ZO6) bottom



What would be different is the Z06 top speed is above what the car could do where for the LS2 it is set at 187 MPH

Also the ZO6 is set with a 7,000 rev limiter which is higer then the 6,600 for the LS2 so it depends on the gear being used and which limit hits 1st.

In answer to your question then could your car hit the stock rev and speedo limits and if so they can be jacked up a bit via tune.

As to stock TM values would have no ill effect at the top end since PCM is looking for sudden quick torque values before TM kicks in which would not happen in upper gears at high speed and that is why if you notice the table ends at 3,000 RPMs

Thanks. Once the new software gets here I'll make a run with the stock top speed limit.

I used to have an excel program that would tell you how much HP was required to obtain a certain top speed but I lost it in a computer crash. I wonder what the HP required to break 200 is on a C6? I believe that as far as gearing is concerned I can reach nearly 224 mph in 5th. That is with the rev limit raised to 6800. However I am not sure that I have the HP to break 200.

Ran some numbers through the simulator and get :

Now that is a nice program.

I did notice that the ratio that is entered for 5th is different than the Z51 model C6 has though. It should be .71:1


Below are the specs for 2005 Tremec T56 6-speed manual, w/ optional Z51 Sport Package

6-speed manual
Gear ratios (:1)
First: 2.97
Second: 2.07
Third: 1.43
Fourth: 1.00
Fifth: 0.71
Sixth: 0.57
Final drive ratio: 3.42

Changing 5th to .71 increases topend to 211 @ 6,450 RPMs at that hp and tq listed above

Looks like I'll need a little more HP and around 10 miles of road to break into the 200 mph range.

Thanks

Go 20 lbs 150 shot N20 and then can do it in 1-2 miles less distance
