Question for you guys. I have and 05 ss/sc running stage 2 gm kit, vibrant header and down-pipe and manga flow cat back exhaust. I recently purchased some 60# fuel injectors. I was thinking about purchasing zzp fuel pump rewire before installing these injectors. My questions are: Is doing a fuel pump rewire absolutely necessary with the bigger injectors and should i tune it before i drive it with those bigger injectors?

 

1. I'm running 80# injectors with my fuel pump and its fine,
2. Yes you definitely need a tune for those injectors

 

FP rewire isnt necessary until your pushing 80s hard IMO
