14B question after auto to 5-speed swap

[Matrixhunter]

Hey got a question i just completed the swap took the 13g turbo out i got a 14b just wondering can i just bolt up the turbo run it on stock boost and not worry about running to lean or fuel cut on the auto 390cc injectors?

I would not run the 14b without upgrading the injectors. At the very least a set of 450's.
You may not get detonation depending on the amount of boost your running but it's just not worth the risk in my opinion.

You will be fine at stock boost on 390's. Wouldn't be worried about it. If you wanted to turn it up to say 15 or so then you would need 450's but for now your fine.
