One more mod before my tune?

jameZ_10 · 09-27-2016, 09:13 PM

Ok last weekend I added NST pulley kit and the Z1 intake manifold. I'm scheduled for a retune On the 8th of Oct. I'm wanting to swap out my final drive to the 3.692. Should I add this then tune or could I add this gear swap mod with out tuning?

Shouldn't you be looking at the 4.10(?) gears? Isn't 3.692 going the wrong direction?

Gears shouldn't make a difference on the quality of the tune, but it will affect the final numbers a little.

3.6 will be a good improvement over the stock 3.3. 4.+ May be more that I bargain for. I've been taking my Z on long trips too.

I really wish I knew others close by with gear mods so I could see the difference first hand
