1G 450CC injectors with auto FPR?

[blujeans]

I recently bought 450CC injectors for my automatic 1G, and I'm wondering if it would be wise/nessecary to also install the fuel pressure regulator off a manual turbo 1G. I believe the PSI on the auto is about 43 while the manual's is about 39.

And before it's pointed out, the previous owner did install a manual ECU since the original one shat itself apparently.

If your wanting more flow from the injectors, go with the AT FPR

The manual ECU will help the car build boost. My auto car had a std ECU in it and it was fun. I put a 16g on it and it really liked it.

I ran 450s for a while on an auto fpr and manual fpr. Both worked fine, no issues that I noticed. Boosted well on a 16g.
I did end up getting a remote tune on the 450s with an 2g maf forwards the end of my time with a 16g. But like I said I didnt see any issues running the stock manual ecu on 450s and either fpr.
