Correcting speedo for 4.11's without affecting custom tune??
I've got 4.11's in a 93 TA however the car has a 94-95 pcm so I should be able to plug in with a handheld tuner and correct the gear ratio. Whats the cheapest one that will allow me to correct this without affecting the custom tune?
Yes any handheld tuner can do that for you. On price im not sure what the cheapest on is per say but you would do good to check ebay or the classifieds for them. Im sure you wont need anything fancy if thats all your wanting to do.
