Default 450cc injectors w/ PR4 OBDI ECU

For the new 2L built motor I am going to be running, I am planning on running it with the stock ECU program during the break in.

I understand I will have to run a resistor pack with the nonOBD DSM injectors I will be running, but what I am curious is to if the engine will run extremely rich with 450cc injectors and a stock program. Can anybody shed some light on this combination or give me some pointers of how to make this work properly? Or would most of you suggest running the stock 240cc injectors during the break in? I want to be 100% there will be no chance of running lean with extremely high compression ratios.

hell yes u will run rich! The ecu will only compensate soooo much.... i've heard 310's are the limit. I can burn a stock program with 450cc maps for like $10 + shipping.

I'd like to have these 450's just to have enough headroom.

If you burnt a program with 450cc maps how can I be sure that there will be enough fuel for this 2L beast? Would it still have stock ignition maps? I just need something to get me through the break in until I install a hondata and have the engine tuned properly on a dyno with a wideband O2.
