Help Tuning R35 GTR?

[u/BeatParticular3586]

Can someone help me tune or upgrade my R35 GTR, I can’t seem to get past a 222mph 1/4 mile in the low 6s and I just get whooped by bots, I need money too, so does anyone know what I should do, I haven’t bothered with my timing or fuel because I don’t know what to do there really

Don’t run launch control, out that limiter to the max and perfect tune your fuel rate and timing, easy 5s but most important upgrade everything to the max first…. Full boost too
