They look aftermarket who knows though maybe it has a tune in it?

 

i wasnt even told that when I bought it [&:]

 

As long as its not pinging under load 87 should be ok

 

what do u mean?

 

If your car is detonatingat WOTthen go from 87 octane to 93, but as long as it runs fine at WOT you should be ok.

 

no it doesnt

 

They are just cobra guages. See how the redline is 7,000? Gts redline at 6.

 

hope he wasnt shifting at 7,000

 

Yeah thats kinda dangerous for somebody who wouldn't know better. Unsuspecting driver shifting at 6800rpm and blowing the motor just because the gauge is wrong.

WAIT! Does that mean his speedometer and tach reading would be off? Because the Cobra's go higher? And I doubt whoever installed them re-caled them to match.

 

**** i hope its the speed isnt messed up!!!
