I bought a set of green top supra injectors which I have seen rated at 315cc. I sent them off to be serviced and the company that cleaned them rated them at 340cc. Which figure do I input into my emanage so that it corrects for the bigger injector? Should I stick with the stock rating or trust what the cleaning report said? I told the emanage they were 340's and took a test drive, went pretty well with no pinging but after sitting for a minute at a stop light the idle dropped and got rough. Any advice?

 

Just play a little with your injector correction factor until your wideband shows around 14.7 at idle.

Maybe you have to correct it a few times to find the right setting, there is some magic self learning in the ecu.
