custom tune and gear change?

[Genaris]

I have an 05 automatic Aqua Blur, I had a magnacharger installed and I am going to get it customed tuned next week after I change the pulley to a 2.9. If I decide to do a gear change, will I have to have it retuned to the gear change?

You don't need to re-tune the engine but... you will need to let the tuner back in to reset the gear ratio to correct the speedometer.

gotcha, what is the best gear to go with?

It's up to you depending on what you want..

Here's a couple of thoughts:

You can also do a search on 4.10 and one on 4.56 and pull up a bunch of info.
