TFI ---> EDIS conversion?

No plans at all to get one. It goes closed-loop very nicely so I'm not at all concerned that it's over-fueling. That's the beauty of MAF - it measures the air mass directly and provides fueling accordingly.

to its limits. that is a problem often fought with the old school 302 and 351 stuff. you dont know until you log and measure it where it is at.

seems like you are in the sweet spot with no active codes, it is obviously not hitting a wall.

putting the larger system on the lower threshold may be ideal as better rich then lean imo....

glad to see its working well...i know supercharging a 2.9 this system might be ideal.

on the other side...puttin this system on a 300 6 might max out the airflow.

that is why i suggested to just leave the 2.9 injectors (if it was a stock unmodified 2.9 engine) before running the 4.0 injectors.

with a bad ass hci combo maxing airflow was an issue with the v8.... especially idle. and generally larger injectors or higher fuel pressure kept it going

Terrible idea - that would have UNDER-fueled by over 25%. Unless you're going to play voodoo with MAF housings, you've got to install the injector size that the calibration specifies.

yes it can be a bad idea. if its idling well and not fat its fine. it is obviously within the tables.
