Speed shut down eleminate? Hypertech?
 

I have a 2000 bonneville SLE and I notice when was flying down the highway that my car shuts off around 105. My 91 caprice use to do that so I bought a performance chip from hypertech. Can I get a performance chip?

I am curious about this on my Bonnie as well if someone wants to chime in....

Intense racing makes an after market PCM....good guys to work with too.

INTENSE is easily the most popular PCM on this forum. Great price, and great support too. You'll want some basics first, like a better intake and a 180° thermostat for starters.

but make sure you get speed rated tires before you start enjoying a speed limit free life - there's a reason that your car was limited from the factory, and it's related to your tires...

tires
 

I'm not worried about the tires. Speed rating on tires are for sustained speeds for hours. I will also be going with some 20s with Z rated tires. How fast will my car go without the speed limmiter?

Re: tires
 

with 20's slower than you are now :)

wheels
 

but chrome 20s look a lot better than the factory 17s 8)

the inevitable struggle between looks and speed. It's a choice that is hard to make.

is it?
