If you are contemplating the normal mods, CAI, Plenum Spacer, Exhaust, De-cats, Y-pipe etc you'll gain better results on the Dyno. Earlier DE models i.e. Pre Revup show better gains than that of Revup. Have a chat withark @ Abbey he knows the best suited performance mods.
If you are planning on FI or after adding NA mods you still want more power and wanted to gain extra Power via FI I'd be looking at getting the older model.
If FI is not your plan then go for the Revup.
All depends on budgets at the end of the day.
