I am thinking about getting a SCT tuner from Hemifever. One part of the questions when buying the tuner asks about the gears that I have. I have 3.55 open right now and might be changing to 4.10 limited slip next year. My question is if I get the tuner now and change the gears later will having the tune set for 3.55 make anything weird where I have to spend the other 150 to get an updated tune?

 

Speedo will be off. Dealer, or, an independent shop with the right equipment might be able to change it, but, I am not entirely sure.

May wanna ask Sean, and see what he has to say.
