I searched through the forums but couldn't find a definite answer. I switched my 110mph gauges to 150mph. As you can image, the speedo is wrong. Can I recalibrate this in the PCM (dyno tune/mail order tune) or is it mechanical?

 

Did you switch the cluster or just added 150mph white faces?

 

What he said. I believe if you just switch clusters then the speedo should read correctly.

 

Just the gauges, didn't change the cluster. Will I need a 150 cluster, or can I have it adjusted?

 

you will polly need the cluster...why the hell did u do that anyways?

 

-White faced 150mph gauges looks better than the stock black 110mph
-Looks 10x better at night
-My car can go faster than 110mph
-I honestly thought that u could edit the PCM to adjust the speedo

 

nope i don't think thats gonna work. You had better get a 150 cluster.

 

Yeah, you'll need the 150mph cluster to go with the new gauge face you bought.

You can keep your mileage the same too to keep it accurate by "swapping" the odometer wheels.

And to answer your question of where to buy them, eBay.

 

What car did the original poster have? V6 or V8? I don't think V8's came with the 110 mph gauges, so that's what confused me....

 

No V8's could get 110 speedo's. If you had a V8 you had to have the Z rated tire option to get the 150 speedo.

 

Oh, then I guess I have that then, cuz mine are 150's.

I knew there was another one besides the 150, but I thought it was 120, not 110.

 

I got 150's..honestlu I wouldnt care if it had a 110, as long as you know it can go faster why do you care to see?

 

110 cars have speed limiters on them and i guess if you get a fast car you might trap over 110 and want to see that at the track i guess.

 

Wanna trade?
