FITEC

Who’s running a FITEC. Just wondering after it has its initial learning is there options for fine tuning?

You would probably find all your answers here: https://fitechefi.com/

I had one on my Fathers BB Corvette. They are tunable, one problem with them is they need a good vacuum source.

How much is a "good" vacuum source?

They are somewhat tunable, but other than some initial "tuning" I've been content to leave it alone. I got 26,000+ miles on mine

They have limited tuning and data logging capability compared to a Holley Sniper.

Goody has installed/tuned one, so hopefully he'll see this and chime in. Here's a thread, not specifically about FITECH, but might give you some insight into FITECHs limitations/capabilities.

I put the 1200 PA on my 500" Stroker engine just to see if it would work on an engine with 4" of vacuum.
It took a little tuning, but works good.
