Is anyone familar with this website? I searched this forum and found (https://www.cobaltss.net/forums/show...in#post1136865) , and according to my results I have stage 2 calibration which my dealer is confirming BUT my redline is 6500 in 1st, 2nd, 3rd.. Any ideas??

Are you seeing over 12 psi of boost? Those are the right calibration numbers . Maybe a bad reflash ? Could be a slow tach too.

 

That is what you are SUPPOSED to have....what you ACTUALLY have may be different. They can scan the car to be positive.

 

^Yep thats right. He said the dealer is confirming that those are in his car .

 

yes exactly, the dealer has confirmed.. and my dealer has given me a "final anwser" that yes I do have the stage 2 flash.. and they do not know why my rev limiter is not 7000rpm but are suggesting the flash may have been changed as the techline person told them it had changed 4 times since the original release (for an 06 anyways)

and a slow tach has been ruled out as I tried it in 3rd gear under moderate acceleration and it stopped on the nose at 6450... the slow tach is only in 1st and 2nd under hard acceleration..

and i am seeing about 14.5 psi.. (i'm in canada..our gague sucks but its between 100 and 110 kpa = 14.5 ish psi)

 

hmm stage 2 is 6450 and stage 3 is programmable to 7000 and in between with gas pedal acutation procedure? boost is 14.5...

Stage 3 rev limiter?
The rev limit is adjusted by pressing on the throttle pedal with the ignition on and engine
off. At about 50% throttle the tachometer will show the current rev limit. Pressing the
throttle further will adjust the rev limit in 250rpm increments.
How high can I set the rev limiter?
The Stage 3 PCM allows you to set the rev limiter up to 8000rpm. However, the engine
will not reliably rev greater than 7000rpm without modification. If you would like to
maintain a rev limit greater than 7000rpm, we recommend installing high-speed valve
springs. Bates engineering offers high-speed valve springs that will fit in the stock head
without modification. GM Performance Parts also offers a set of neutral balance shafts
for high-rpm operation.
stage 2 is all you really need your fine. and its still snowing in windypeg anyway...
