Default factory 28lb injectors w/ h/c/i

I just finished a heads cam install on my car and was wondering if the factory 28 pound injectors will hold up. I was told by my tuner they should be good, but I may run nitrous in the future and I was wondering if they will keep up with the with shot. I bought a set up 36 pound injectors just in case.

As of last summer my car had the factory injectors, small cam, and a 150 shot and put down 530whp. Just for comparison..

I just did a H/C/I also (465rwhp) and the tuner said my 28 lb's were fine. But they where at 98% duty cycle. He says that he runs them harder than that! I am wondering if he knows what he is talking about?

They should hold good, but its always good to have a little extra room just in case you go bigger on your shot or setup.

GTP's on Ebay huh? I will look into that.

Update; just looked on ebay. So this GTP is 6 cyl then. Singles are about $15.00 ea. So thats only about $120.00 for the set of 8. I like it! Can you cofirm part numbers for me, as there seems to be a few different ones.
