Do I have to change injectors on my car with T-rex cam ?

With the stocker 26# injectors, theres a very good chance youre gonna be well over 100% duty cycle with that cam. You can chance it or you can play it safe. If you decide to get injectors, look bigger than svo 30s. Im already over 105% with a mid sized H+C.

I'm going to look into 30+lb (probably 42lb) injectors for my TRex install. If you ever plan on spraying it or pushing it to the max (and why wouldn't you with that cam???) it will save you the hassle of the install and re-tune down the road.

i am @85% duty cycle on svo 30s with stock heads, headers and a z06 cam. so for any well done big cam, you're gonna need more, way more. i've seen svo30s run out of flow at ~430rwhp on a dyno, and you just see the power flutter. svo 42s are trivial to tune, have perfect drivability, and can support to about 480rwhp in NA trim.
if you can afford it, get the flow matched ones.
