Quotes from their page:
"Does JET Performance remove the speed and rev limiters?
It depends on the specific vehicle. On most chips, we eliminate the top speed limiter. The rev limiter is raised when possible and is completely dependent on the application."
( I called Jet and confirmed that the Bonneville chips REMOVE the top speed limiter)
I'll be installing mine this weekend, hopefully.....Thanks, Hector! Saved me some cash on this one. If you're thinking about one of these, get ahold of email@example.com
or pm 99bonnevilleSE on here. I'll re-post my perfomance data after install this weekend (if it gets here on time!)
