If I were to up my S/C pully from 9.5 psi (I only see about 8.5) to about 10psi (IceNine had a 12psi pully and sees 10psi), would I be ok with only getting bigger injectors? 550cc? or would I definately need fuel management?

I know IceNine said he was leaning out at 5500 with 10psi and the stock TRD injectors.

I'm not sure of what the TRD Reflash is capable of.

I would definately get a wideband O2 to monitor, but would I need an ECU?

It would be highly recommended when changing the injectors.

 

^^agreed...you don't necessarily need it per say, but it would be a good idea

 

If your car lives at redline you can kiss your motor good bye without injectors. If it doesn't you'll get a few thousand miles out of it (could be 1k could be 30k) either way its not worth 3k in parts and labor for a $400 part you can buy now

 

whatever you do, tuning is the key. just because you bolt on parts doesnt mean it all works together, some may actually hurt your car.

dont take the easy cheap way.
