Default Tuning after Engine Rebuild?

Hi, before anyone says do your research, I have been looking constantly for the past couple days and still have not found an answer. I have a 2004 Wrx and just developed rod knock recently (Ej205). Car was not driven after the day i hear the knock. I currently have the motor apart and everything looks okay. I went to my local subaru shop, also called Perry Tuned in tiverton mass, and am having the motor rebuilt with a new crank, Weisco forged pistons, and Acl race bearings. My question is will i have to have the engine tuned again after the motor is all put back together? I know some people say always have it tuned but they charge $400 and i saw some people saying i didnt need to have it retuned since the motor didnt blow up. In a couple weeks i will be getting a vf48, bigger fuel pump, injectors, and bigger tmic. So the problem is the motor will be done before i will getting those mods and need to know if i can drive the car for a couple of weeks untuned. And yes i will be having the car tuned when i put the bigger turbo and **** on. Also for anyone wondering the only performance parts on the car is a 3" Catless TBE, Catless Uppipe. The last time i had the motor pulled apart (only a month ago), I did oem headgaskets, Arp Headstuds, New clutch and flywheel, New valve seals and had the valves reseated, and had the heads shaved by B&K Machine Shop.

Default Tuning after rebuild

I would not drive it if you do not have the money to rebuild again.
