Yeah, or you can up your fuel pressure (if you have an AFPR) and have it retuned. this will lower the duty cycle on the injectors. I ran the stock injectors with that cam and LE heads and had 113% duty cycle @ 45psi.

I say run higher fuel pressure. Get higher lb. injectors when you really need them, like for heads or blowers. I'm running 45 psi on my newly completed overhaul with a 230/242 duration

i say get it scanned and if your duty cycle is 90% or over for the car to be in tune get new injectors that are bigger. your asking for a lean condition and a blown piston if you run it at more than 90% duty cycle often.
