Restrictor / Limiter

[adz]

Im not sure as to whether all models in the US have this or if this is only on mine due to it being an import. (im from the UK)

 

My silverado has a limiter on it, the speedo only goes up to 100mph and once you hit that it wont let you go passed it, im wanting to start to modify the engine for a quicker quarter mile time but im nearly hitting the 100mph on the clock already and once it gets tuned hope to go passed it so i need to get this removed.

 

Has anyone of experienced this before and any idea how to remove this?

 

thanks

If there are no local custom tuners over there, then get a Diablosport handheld tuner.

My 02 and 04 cut out around 98-100 mph. I think the computer controls that. And yes, I found out by trying to go faster.

I think all/most of the tuners custom or not you can remove/increase the speed-limiter.

 

I agree with Vmax if you cannot get a custom tune I also recommend the Diablo Tuner. It's the hand held I would have gone with if I didn't have my Blackbear tune.

 

Welcome, Good luck and we want some pics

As for a tuner here are a couple sites. I don't know if Justin (Blackbear performance) will ship a datalog cable to you, but it would definitely be worth you time to email him and ask. This would give you the best bang for your money.

If that doesn't work out then go here... Diablo Sport

 

 

As for pictures. Get a photobucket account. It's free.

Upload your photos there, then go to the "My Controls" link at the top you your screen and then use the "Edit your signature" link

The car companys claim the speed limit vehicles according to the speed rating of the factory tires.

 

Most any programmer/custom program will remove it.
