tuned my ecm but not TCM
Hello Everyone! So long story short. I have a 17 ss and they are a pain in the ass to tune.To tune your TCM you need to send it in to get it unlocked, so I only got my ECM tuned. My question is....will my car feel much better with a tranny tuned? Will it cut any time in my 1/4th mile? thanks
