I'm not too sure about you guys, but JZX90 (my cousin on GTP) uses NOS for his JZX100 1JZ-GTE with a T88-34D Turbo. Some of you may know that it's a large turbo which means large turbo lag. So for little sections, he will have the NOS running permanently for that specific 100secs (Usually the whole D1 Section) for the D1 Run only! (Saves NOS & Cash). Usually running at maybe 2 PSI. So it, cuts out the lag. But doesn't provide ridiculous HP overload that it unbalances the whole cars setup. This is what GT6 is missing, and what i presume is, people will be creating a setup that permanently runs NOS for a temporary time. Most likely for Wheel users.
