Message	1)Looking around at pricing, 555's and 740's seem to be fairly similar in price. If upgrading, would it not make more sense to go for the 740's in anticipation of future mods, or do they just not work correctly with a lower mod level? 2)I'm trying to figure out what injectors are currently in the car without removing. If I send the serial number off my ECU will JWT have archives to tell me what injectors the current program was set up for? My car had a couple mods that I wasn't told about when I bought the car, and I'd hate to order new injectors and find the same thing already installed.
