I ran my Mikael and RGR package with larger injectors and ran very rich while I was waiting on my chip. If you dont change injectors you will run ok but a chip will make it run better. If you change injectors or MAF you will need a chip period
I thought the entire point of the venom kit was that it came with it's own computer system to allow you control all of it from inside the car? If you don't get that... what possible advantage does the venom system have?
