I have a talon 1g and I will use a 2g mas with evo 560cc injectors...I need to know if I need an safc to control the injectors or I can just run it without any problems!!!

 

yes

 

installing 2g maf on 1g will cause fuel curve to go lean. installing 550 injectors brings fuel curve back very close to stock. this is car specific question. I have seen this combo work quite well without AFC.

 

Pretty close is not on point, might as well do it right the first time

 

If I use 510cc injectors instead of the 560cc???

 

Had the 2g maf and evo 560cc injectors in my 1g. Worked good even without a tune but it will be a little rich. Def get a tune afterward to get more power.

I wouldnt use 510cc injectors because you would run lean. 550/560 is perfectly fine.
