It's recommended to have 550cc injectors for a 77 or smaller pulley (assuming you have a stock crank pulley), although some guys run a 77 with stock injectors. Some will also recommend colder plugs, since with a 77 and tune you'll be getting a nice bump in power. For a street car, at the very very least you'll need a 010 pump and an upgraded heat exchanger for a 77mm. For track/drag you'll need a lot more cooling. I'm not even sure how long that combo will last the street, also depends on where you live

I would recommend injectors, colder plugs, bwk and I would go straight to a Tank & KC. You'll see if your watching your IAT's how quickly the 77mm will make heat and just kills power. Do some or most not go that route, yes. I wouldn't recommend it unless you have other items that compliment it or else even on one full throttle run your going to be very high IAT's.

Stock injectors with a well functioning OEM fuel system and you will be fine.

Only the 06 CLS has green injectors from the factory which are rated at 525 if I remember correctly.
