This is true. Solve ecu options first, see what exhaust/injectors/intake/pump do... Then turbo (which will probably mean end of cvt)
But i dunno if you can even properly dyno a cvt?? Obviously you can see tps, velocity, afr, psi, so you could make it healthy but getting a 1:1 ration would be hard. You can force it into "gears" but who know what ratio they would be if its variable.
