You didn't say if yiou data logged for a custom chip?

Fuel is 18 to 19 psi
Makes a difference in how to calibrate a chip, get a reading. 18 should handle this motor fine.

Did run while at @ 0 would fall on its face when Iwould try to accelerate so Brain recommended advance timing as much as 12 deg (seemed wrong to me but I tried it and it helped)
You were right and he was wrong.

When I first did this swap with the stock TBI motor several years ago Affordable Fuel Injection recommended me doing this way and the wiring harness was not built to add one in.
Wrong again, they just sold you one that was built that way.

I explained my who build to comp cams and they said this cam would best fit my needs
Well at least that was good info. Marine cams are great low idle, low RPM tourque cams. You would have been batter off with a stock TBI and not bored for the low RPM response.
