FWIW, my LS ran 15.56 @ 92.x bone stock. Sig has my time w/ just the CAI (and a little cooler temps).
HIs spedometer could be off too. My brothers wife had a Taurus that once you got above 70 mph, the actual speed of the car would be about 7-8 mph faster than what you were actually going. Just a thought.Quik LS said:hate to call BS here - but we've tested more than 20 LSes with radar guns - 143mph is it.
- lowered 145
- bodykit and aero 147
all the pre-03 V8s hit 142 - 143.

Quik LS said:right - 03+ are electronically limited to 133mph - with code in the PCM.
you can remove it with the SCT XCalibrator PCM flasher.
Quik LS said:right - it's not a rev limiter - it's a speed limiter. With it removed, your car (if it's a V8) should be able to hit the 143mph mark.
Make sure you have the right tire rating for the speed
Quik LS said:I believe that most non-sport models were sold with H-rated tires - since they were speed limited anyway - so the issue is if you have H-rated tires and remove the speed limiter bad things could happen.
