HELP!!!! Stock injectors not good enough?!?!?!
HELP!!!! Stock injectors not good enough?!?!?! Well, ****!! I hooked up my NOS 5177 kit yesterday afternoon and checked with my tuner before filling the bottle and taking it for a ride. He said the stock injectors weren't up to par to use the kit!! I was like WTF, I have these plans to go to the track this weekend and hit bottom 11's and now this!! I had NO idea that my cars injectors with only a 225 cam wouldn't be able to support a 100-125 dry shot. Has anyone else ran into this problem? This sucks big time, anybody know a good place to get some SVO 36lb hr injectors, that's what he said I'd need.

BTW: you may want to get some NGKTR6 plugs
Anybody else? I know this kit is designed for stock injectors, the 225 cam isn't pushing the injectors that much harder is it? The stockers are 28lbs right. I need to figure out what to do, either tell the guy I'm gonna bring it up to the dyno and check the A/F ratio on the spray and hope he's wrong, or bite the bullet and get bigger injectors. I thought there were alot of guys running a cam and dry kit on the stock injectors. All help will be greatly appreciated. And thanks to 99PewterZ28 for your input.
You can hook up an obd2 scanner to monitor injector duty cycle. That'll tell you what % the injectors are being driven. With my 2000 z28 (26.4# injectors), I run a 100-shot dry and get up to 85-87% duty cycle at 5900rpm, but I don't have many of the other power mods (cam, headers, intake, etc). Anything over 90% and your injectors are basically on all the time. I think your car's got 28# injectors (2001).
Id be willing to bet you are very close to maxing your injectors out. I would swap them for some 30s minimum...better yet some 36s. That will give you plenty of room. DO a fuel pump as well.
