My W11 engine is equipped with a DDM cai, 15% SC pulley, 2%ATI crank pulley, RMW shorty header, Milteck exhaust, DT bypass valve, and a Jan Tune. In your opinion, will 380 injectors be beneficial? I don't plan to install a cam until my car reaches 50/60 thousand miles...maybe. As always, TIA for any help/information.

 

A question for the question, was the tune "canned" whereas there was no A/F monitoring performed?

 

Personally, yes. They will just make things safer at high RPM with your 15%/2% combo, until you do your next upgrade.
But... Double check with Jan first, while the factory tune can self adjust to compensate for the extra 50cc's of fuel flow, verify with him that his tune will also, and there's not some kind of lock on the fuel scaling.

 

I'll agree with the "have a conversation with Jan." I would think they could be beneficial, assuming you re-tune for the larger injectors.
