Need help tuning 37# injectors.. i just picked up some lucas 37# injectors, i havent put them in yet but im going to very soon..what tables do i need to change? could someone kinda walk me through this? also will the new injectors mess with my a/f ratio any? will i have to re-do the PE table? thanks!
Use Redhardsupra's injector spreadsheet:

You only need to adjust the IFR table. If the new table is properly dialed in, you shouldn't see any difference in AFR.

ok now i got another question...i got hp tuners 2.0 and when i go to the ifr table and go to the unit conversion deal to calculate my new tables for me it wont work! man this is pissing me off..this is what it says to enter..Current inj flow, Current fuel pressure, and then it calculates the new fuel pressure and new inj flow? what the hell am i missing here? i cant figure this **** out..i looked at the suite info on hp tuners but there directions do not work at all..please help..
The calc is only going to show you max ifr at a given pressure. It will tell you the max flowrate your new injectors will be capable of.
For your IFR table you need injector flowrate vs MAP for each MAP value (increments of 5kPa). Open up your editor and go to the Engine -->Fuel Control -->Flow rate vs kPa tab. Enter your new injector values in Redhardsupra's spreadsheet and copy / paste the resulting values into your Flow rate vs kPa table. Hope this helps you.
Good luck with your new injectors, I have the Lucas 32s and found them very easy to tune for.
