I personally recommend anyone looking to buy injectors and a pump to go with 80s and a 450 . And of course the matching chip to run them . This way you buy them once and you are good for awhile instead of being like me and going from stock to 42,60,80,120s, to finally 160s . You will still be able to idle and drive fine on the street but will have that section covered from future upgrades. It is also recommended u get a adjustable fuel pressure regulator and a -8 return line . If you can’t afford them then just save up till u can afford to upgrade. I’m telling you it will save you money in the long run if u upgrade once and right instead of a year down the road buying another set of injectors and another pump . This is just my opinion that doesn’t mean much so take it or leave it just keep on spoolin ether way bud .
