I have a 2000 C5 with 26.5lbs factory injectors. I have a H/C car with 400rwhp and I'm wondering if I need to change my injectors since they are so small. If so what should I go with? Thanks

If your dynotune with the head/cam held a correct a/f ratio....you're fine with the stock injectors. No need for larger ones until you run out of fuel.

If you have access to a scanning program (EFI Live, HP tuners) log the injector duty cycle and see if they are being max out. You'll more then likely fine, but logging them is the only way to know 100%.

that in no way, means that this guy needs them. I dont think you are reading the IPWs logging the duty cycle correctly. althoguh you MAY have a bad set of injectors....i would check on my scans, then swap to another set of 26#ers and check again.
