In my state vehicles 3 years old have to pass emissions tests, in some counties you have to get one every year after the vehicle is three years old until it’s 25 years old. Some counties don’t have emissions requirements but I’m not fortunate enough to live in one of those. I will look into the LT4 injectors and fuel pump and the MAP sensor. The kit is “bolt on” but anyone who’s ever worked on any vehicle before knows how that goes. I did also get an electric oil pump which will return into the oil fill cap instead of having to tap into the pan as well. As far as the air box I haven’t been able to find anyone who has installed this particular kit on this particular truck but there’s no air filter relocation in the kit and from what I’ve read on their website it doesn’t have to be relocated.

Kind of jumped the gun about 6 months ago and bought a single turbo kit for my 2018 double cab 5.3l Z71 package. I’m still planning on installing it but have decided to wait until the warranty is up in roughly a year or so before in install it. In the mean time, I’ve decided I can probably gather a few other parts to make fuel and air delivery better and also wanted to ask about high flow cats as I’ve read in some places that factory 5.3l gm cats are high flow? I’m not planning on running crazy high boost just wanted something fun to toy around with and maybe it will help with towing every once in a while too. In any case, I’ve read that bigger injectors will help but if it’s still going to be a daily driver. Do I need to do this? I’ve also considered putting a catch can in, cold air intake and maybe a fuel pump depending what everyone here thinks? I’ve had a range 4cyl disabler in the truck since it had roughly 500 miles on it. Plan on having it disable through the tune once I have it tuned for the turbo install. Really just looking for some input and ideas here since I’ve got a little bit of time for the install. Would rather be over prepared for what I will need I guess. Thanks in advance.
