Question Bigger Injector with light mods?

I'm planning to get a Unichip or Utec. My mods include:

catless up-pipe
Axle Back Exhaust
Apexi Power Intake
Intercooler hoses

I'll be running low 91 octane
My question is, do I need to get bigger injectors because of the low octane fuel?

Nope.

Fuel flow, and Octane rating have nothing to do with one another.

You only need larger injectors when you have more air, ie. with a larger turbo.

In your case I'd recommend an ecu reflash. Cobb's AccessECU is worth checking out @ only $395.

The uppipe and IC hoses with a reflash would help, but intake and axle back are not worth the gains you get and debateable if the intake leans out your car too much.

Does this mean I should stick to a tuneable engine system or upgrade my exhaust?

finish your exhaust system...get a downpipe. My .02. And maybe a high-flow cat or 3rd cat eliminator.
