Hello, is it possible to go slightly larger injectors with still using stock ecu and no drivability issues? Only saying cause one of my injectors is leaking between the top plastic piece and metal part so I’m just wondering can I go from 35 to something slightly higher?

There is a search bar when you get on this part of the forum I've used it to search and you can go slightly higher then stock, but your probably going to not gain anything really. from what I've read i would stick with stock or stock replacement unless you change your ecu and go that route

With the stock ECU, the only way to use slightly larger injectors (like 45's or something) is to have an adjustable fuel pressure regulator so you can lower the base fuel pressure to make the injectors flow close to 35 lb/hr so it's not running constantly rich (which is what it would do with 45's and stock fuel pressure). The downside to this is you need the AFPR ($89) plus you don't get as good of fuel atomization with the lower fuel pressure.
Also note that larger injectors don't add any power. So if your current injectors aren't completely maxed out, you've gained nothing with larger ones.
