Hey guys, doing the hotcam kit and LT's with true dual exhaust on my 99 SS in a week or two, while its away for the winter. I also have the mods in my sig, and may very well be upgrading to a larger TB. Should I go to something like a 30 lb injector? If I remember correctly, 99's had the 26lb stock. Thanks guys!

 

450+ rwhp is about when you need to start thinking about injectors. Your stocker should support your mods fine. You can always check injector duty cycle with EFI live or other means of computer tapping.

 

You stockers will work fine. You are correct about having 26# injectors. Throw on a LS6 intake and you should be good for around 380 rwhp. It sounds like you have a nice car. Good luck.

 

I still have on my stock injectors and they work fine for me. Are you buying a kit for true duals or are you going to make it yourself Mike94LT1?

 

Making them myself... ...errr.... having someone who is a competent welder make them for me I have several plans I am working on, and I am going to make a thread complete WITH pictures in a few minutes, if this damn camera thing starts working again.
