Common there has to be a Vehicle Speed Sensor Buffer out!
 

I've been looking everywhere and I can't find out for our cars! I want to switch tire size but i don't want the change in the milage etc. They have buffers for F-Body's and GM trucks but no 4t60e's or 4t65's!

I dont want to reprogram my chip becuase when i get a performance chip i dont want it to f*** up if this chip is different. Unless it works off the main chip for the speed sensor.

I find it hard to believe there is none out there! Can we use a different one?

http://www.planetperformance.com/pro...5&sf3=FIREBIRD would that one work? Some of the F-Body's had 3.8's

I think i found one that works.

We've got a good unit for half that price on the Electronics page of our site at www.INTENSE-Racing.com.

Hope this helps.
