We can usually get a little farther with a Walbro 255 HP on a DSM than a Evo(around 420awhp on an Evo versus 440-460awhp on a DSM), but it is mostly lilkely because every DSM guy has their fuel pump rewired with a big wire going directly to the battery, while almost none of the Evo guys do that.

You definately need more injector to make the same power at a higher RPM. The more RPMs, the less available time an injector has to fire before the next revolution.
