I've run my original MEFI 1 for 25 years and literally hundreds of tunes loaded and downloaded. Zero issues, not one. I'm not sure how much more bullet proof it can get.

The 1.32 ratio is a tall awkward ratio to use and a 21" aluminum prop is a poor choice. The hub is spun or the blades are merely flattening out. Do not go up in pitch yet. You have no solid...

MEFI 1. It won't likely be locked. Most MEFI 1 were not. I don't have a TB tune for a small block but have one for a TBI 454.

I think you might be overthinking this a bit. Make your 383 and...

As Griff asked what is the max HP rpm? Prop towards that. Rather than adding pitch in this scenario I might suggest you increase prop diameter 1/2" to maybe 1". The increased diameter will offer a...

Need more data.

What year motor and serial# (BUP style...inside joke).

Is the motor modified, crate motor or a take out?

What is the WOT rpm?

Has the ECM been tuned or tweaked?

Personally I would ditch the aluminum 4 blade. If you went to a Rev 4 I would get it in 19" pitch. It has a LOT more blade area. A 21" Rev 4 would load your motor like a 23" Mirage. I know 19"...

My question would be what rpm are you running with the 21" Rev 4 at WOT? Are you near or at peak hp / rev limiter?
