need a tune?

[01 PR RAGTOP]

I'm putting 3.90's in a auto, will I need a tune? Will the shift points be o.k., or will the computer be out of wack with the new gears? Getting a programmer sooner or later, thinking about SCT. Is there a big advantage with the LiveWire over the 3?

You will need the tuner to adjust your spedometer. You're shift points will be fine, but the speedo will be off...you'll be going slower than it says you are and racking miles up quicker as well.

shift points will be fine, sct has great products but some tuners have issues with them, the excal2, or excal3 are good if you plan on having it dyno tuned in the future...

So whats a good tuner if your not planning on having it dyno tuned?
