    We would be happy to help with a tune update. I would say if you added a corvette servo, that would be one of the reasons the tune would need to be updated, that will need to be factored in with how the tuner adjusts the shift firmness.

    We update our tunes for free as long as you own the vehicle. You would need to email in so the tuner can take a look at what has changed since the last tune.
