Hi all. Car is a 2003 C5 Z06. Cracked #7 cylinder/water jacket, so a basic forged engine rebuild is underway. Enough stuff is changing that the car is going to require a retune. Using EFILive but I've read thru plenty of HPtuners threads as well.

I have been running on the previously noted injectors at my tuner's recommendation. Going to tune myself this time around. I am digging into the tune now... some of the values he used for the injector settings don't jive with the provided info sheet for the injectors. I am trying to figure out if the tables are most likely incorrect or I'm not understanding the table descriptions exactly or something else I'm not considering.

There seems to not be a lot of definitive info on these injectors. As a Plan B- before I dig any deeper into this, do you guys think it would just be a better idea to get some comparable 36-42lb/hr injectors that are well known or already used on OEM GM applications? I was thinking LS3 injectors or something along those lines.

IFR table is pretty straightforward, not worried about that. I been mainly focusing on B3701 Injector voltage offset and B4005 small pulse adjust. The injector sheet provides a basic voltage vs offset spec (see attachment). Really nothing for B4005 other than it says "Minimum linear PW: 1.56ms", which I assume to mean it behaves linearly above that PW.

What conflicts me is the tuner set values don't align with the spec sheet. The values that my current tune has, I have ran across a couple times in my online searching, but it was mostly "I found these settings online somewhere" vs some real discussion on the topic.

Anyone who has tuned with these, any tables you can share or tuning tips? Still open to buying a different set of injectors if that's the best way forward. I don't want to obsess too much over little things that don't matter to much, but I'd like to get these right and hopefully myself some time and hassle later down the road.
