I am getting my quad ready to be tuned our speed shop out here uses an o2 sensor on there computer dyno to tune I have a basically stock engine very fresh running FMF exhaust and have 34 and a 38 mm carb would the spacer make much difference the tuner is going to do air box mods and possibly port the cylinder

I'm trying not to spend a lot more money on this quad which carb should I use my tuner says it doesn't matter because he will set with the o2 sensor the 34 fits better and cable seems to fit better in the quad any opinions
