I don't want to name any names, so I will label tuners as A and B. Here's my scenario.
Tuner A tuned my original setup after getting the Paxton with ID1050X. During initial idle/neutral rev logs, they mentioned how the a/f was richer than they expected on 91 octane. They made adjustments, tune was fine until burning out my OEM fuel pump.
I recently switched to a Sai Li return system, and switched to Tuner B. Starting off on E85, I set fuel pressure to what they wanted. 50psi at idle with vac line off the regulator. Tuner B is also perplexed at why my initial logs are so rich. Even after removing 10% fuel, it's still rich. Tomorrow I'm going to be pulling the injectors to make sure the part number on the injector is actually the 1050x and not something else.
Is there anything else I should be looking at? I find it interesting that both tuners have the injector data for these, but it's still rich. They didn't give me anything else to go on besides double check the injectors.
Setup:
Paxton with 3.8" pulley
Boss IM w/light port job
JLT CAI
SP off road headers
ID1050X
Sai Li Fuel System/E85
