Chris is running 30lb injectors and Tom is running 36lb injectors respectively. Their power numbers are well known. The injectors are not tasked in either case (especially Tom's)
Now running 42lb injectors to make much less peak HP (and peaky it will be with their stated turbo but that's another story) is serious overkill 90% of the time!
The ignorant crack about ease of tuning to run smaller injectors really shows the lack of knowledge on their part. The smaller injectors were picked for a specific reason. They supplied more than enough fuel (as well dyno proven and tested) and give great drivability and efficiency the other majority of the time you are not in heavy boost.
Tuning the A/F is tuning the A/F regardless of injector sizing. Intentionally picking oversized injectors for the application is what shows lack of tuning/design ability.
Hence I will be swapping 30's in.
I'm still baffled how people say there is no such thing as to big! I can't figure out when the EEC sends a 2ms pulswidth to a injector that is limited mechanically to 2.5ms (3.5ms on my lucas delhi injectors) it will run right! Bahh!! 
I offer PnP Heads for all durtec's details at PnPheads.com or jesse@pnpheads.com for details.
