Where do I find Injector data for tuning
I installed Siemens Defi 80lb injectors on my turbo truck. I cant get it tuned because I cant find the injector data for them. the tuners in my area keep mentioning to me that I need to get it before I can progress. I have done a ton of digging with no result. Where can I find the info I need to get my truck tuned. every build thread goes from installing injectors to being tuned with not much info on the subject.
Thanks in advance,
Chris

I wouldn't let someone tune my vehicle if they didn't know how to find the data for a common injector. Try googling "Siemens Deka 80lb injector data"

There ya go, just make sure whoever is tuning it changes the offset values correctly. Unlike what is mentioned early in that thread leaving them stock is not the right answer. If you are running a return system you can get away with it somewhat as lower idle fuel pressure uses a higher inj pulse but if you are returnless they will try to misfire with stock offset and high fuel press. With that size injector you should be on a return system anyway.
