I'd like to remove the 150 mph governor on my car. I've got W rated tires on it now, and hitting the electronic wall is pretty annoying. What do you guys suggest? I come from the BMW side of the world where everything's a reflash. I'm also in Bay Area NorCal if that helps.

funny I know a guy here that hit 161mph. The vid is on youtube. maybe its a cali emissions thing?
The car was sold in Michigan, and I can't imagine a reason for having a governor on the car emissions-wise. I think they're all California-OK to prevent resale problems. It's worth noting that mine's an '06... Do the LS2 PCM's have limiters?

The '06 LS2 factory limiter is 150 mph w/ the RS-A tires.

Yes, a reflash will take care of it; shoot me an email.

I always wondered how abrupt the cutoff was. When power is cut does it upset the car at all? Ive' been in some rentals where the power shut at around 100. It would disturb the balance of the car. I'd hate to experience it at 163mph.

I know I've done 161 or so the speedo said...makes me wonder if that was really the case. Stealth said the factory limit for on '06 was 150mph, but I have runcraps. So this leads to another question...did my dealer jip me on the FG2 package? Wasn't it a dealer installed option? And the car I did buy came from a different dealer. Gotta see if I have my sticker...

:confused: :hmm:

I want my FG2s, and I wan'em NOW!

Could be a speedo cal problem. My speedo is consistantly 2mph off of the GPS read out around 80 and I've gotten 2 tickets to prove it. I think others have had this too. Then again, I could be wrong.

To get rid of the limiter, change the tranny or rear end, or ride on 26' yo.

Was your car sold new with RSA or F1 Supercar tires on it ?

If your going down hill or making big power there are two limiters on my '05 PCM. First at 168 MPH, the second at 175 MPH. :)

Dunno, haven't found the sticker yet. The car came from dealer A, I bought it from dealer B, dealer B traded out a redline for my raven. For all I know dealer A could have kept the FG2s...

Hi. I have an '06 and am interested in the PCM reflash for the speed limiter. Is that screen available at a dealer? I work at a Chevy dealership and have cooperative techs but I need to point them in a specific direction. Any advice would be most welcome. Thanks, Paul.
