Just ordered injectors, almost nitrous time!
Just ordered injectors, almost nitrous time! Ordered a set of Flow-matched SVO 30# injectors from New Era. Damn stock 26# holding me back from my dry shot hopes. So with that purchase I had a few quick questions. They do just plug right in don't they? and TR-6's should be good for up to a 150 shot?
My brain has been escaping me recently and I wanted to make sure I was as correct as I thought I was.

They do just "plug in" in the sense of installation, however unless your tune is changed, you are just solving one problem (fueling on Nitrous) and causing another (fueling N/A). Yes you will get more fuel because they are bigger, but your tune will be wack.
You need to change the IFR in your tune to reflect the new values of your injectors so the PCM knows the correct amount of fuel its sending to the cylinders.
For the effort and I would recommend 42's and do the tune, that should get ya in the 150+ range fairly easily.

I have HPTuners, and I know how to change my IFR table to accomodate my new injectors. So that shouldn't be too much of a problem.
The SVO 30#'s seem to flow around 36#'s on the LS1 fuel pressure. When mine come in the mail I'll see exactly what they flow at and I'll make sure to report back. That should be sufficient for a decent shot. I didn't want to have an issue with low throttle conditions and minimal flow as I don't intend on spraying all the time so I didn't shoot for the 42#'s.
Mods aside from this future nitrous are: LS1 intake, Mac Mids, SLP LM, Lid
I shouldn't be stretching it too far, I wouldn't think.

Its plug and play then 
I used redhardsupra's injector spreadsheet for the new values, worked flawlessly.
Comparing the old 26 # spray logs to the 42 # spray logs is certainly interesting. I went from 106% IDC (75 shot) to mid to upper 60% IDC.
