You need to ask the person writing the tune what kind of fuel pump you need, if they have done tuning they should know when the car needs more fuel...

hey man you dont necessarily need colder plugs. The v6 comes with a one step colder plug so you should be fine. If you want the cheap insurance just get a one more colder step copper plug from sparkplugs.com

and i'm almost certain the stock fuel pump is up to par for 100 and 125 shots.

The six uses different plugs than the GT. A stock pump will supply a 150 shot on the GT, I don't know if the six pump is any different on output.
