Stock injectors will be fine for that set-up.

The LT4 knock module is always a good idea, even on a stock car. When you start adding headers, aftermarket cam, etc., it becomes necessary.

LT4 module for sure. If you wanted to bump up the injectors to maybe some 30# it wouldn't hurt.

All you want is the module i have one that has been in by box for a few years . I got it at the stealership. if you had lt1 edit or so you can make the stock knock be less sensitive which is the same thing the lt4 does. with may want to look into that. For the price of the injectors you are looking to buy i would ge a regulator and or a new pump. just my 2 cents
