Need to change injector settings with fuel pressure change?

[Revdoc]

Car is a 01 Z06 with ECS supercharger kit, otherwise stock. 3 bar SD tune, no MAF, 60 lbs. Siemens-Deka injectors that came with the ECS kit.

I paid a local guy to put a baseline tune in my car, mainly because he had the Greg Banish DVD so he could setup my injectors correctly. Since then I have been tuning VE and making good progress. Now I have swapped in a Walbro 255 from Racetronix and my fuel pressure is around 5 psi higher than it was with the stock pump. Of course, this means my AFRs are all richer than they were. If I modify the IFR table to reflect the new fuel pressure, will that save me from having to rework the VE table? Or I guess, what is the proper way to fix this situation? Do I need to change any of the other injector values?

Fueling changes should be dealt with in fueling tables,
not airflow tables (VE etc.).

I think the best solution is a manifold referenced FPR
that will stay where you set it. This also can help the
big end and little end live with each other, your idle
fuel pressure will fade and that's good for big ass
injectors. And if the rail pressure is really manifold-
constant, your IFR table becomes dead simple. At
the cost of some plumbing.

You might like to play with the injector spreadsheets
by redhardsupra (Marcin), they seem to be pretty
popular and useful (and free).

I'm wondering why you have a 3-bar OS instead of a 2-bar. Wasting some resolution there unless this build is totally tempor To me, the answer to your question depends on if your fuel pressure is flat across an entire pull. If so, your IFR table change would make sense, however I would caution you to watch it throughout an entire pull. Think what happens if your pressure noses over up top some and you whacked the entire table.
