I have a 04 lly I had a local shop who does chips to remove limiter but later I had my truck reflashed . I lost the top speed i had I went back and they said they would have to order a program using the new codes the dealer put on my truck. Is there an economical way for me to remove the top speed limiter.thanks

Programming is the only way. Unless you start fooling the computer on the speed input and make it think you are going slower than you really are.

Just out of curiousity, why would you want to take 7000+ pounds of truck over 99 or whatever the speed limiter is these days?

Well I feel like my speedometer isn't wearing correctly unless the needle is able to go clear to 120!

LOL...Ok.

Dont take it the wrong way, I am all about the speed, just never really was in the truck, never even hit the revlimiter. Keep the 120+ runs to the vette

A LLY Predator tuner will do it for about $350. Also get the benefit of using it as a scanner in addition to being able to add extra HP.
