ECU and TB swap Q's/suggestions

[Viper588]

Hey guys Ive been planning to turbo my 4g64 for a while and am going to do it when the weather starts to warm up. Ive started to pick up a few of the last items on my list and have a few questions. First off I am not going to be going to the track or building a huge amount of power. I will be aiming for somewhere around 250 in the end. The main questions i have and am looking for suggestions on is the ECU and injector/TB swap. Ive read that i can keep the stock ECU or swap it for the Turbo to get better timing, knock support etc.. For my goals of 250 (which im not aiming for as soon as the swap is done but in the future) is it really worth it? The same for the TB and injector swap, i feel that for what i consider to be modest goals compared to what i see most people on the forums doing just going with The stock ECU and high impedance injectors would be simpler and easier and still reach my goal. Any input would be appreciated thank you!

(TL;DR - To make 210-250 is ECU swap and TB swap necessary?)
