Mike I put together a Megasquirt ECM conversion for the GT40. I was planning on upgrading engine with a stroker crank at some stage. My original Ford EEC1V computer was also having intermittent heat soak problems. The injectors are large enough PCM used 24lb injectors most automotive applications of the 351W used 17lb injectors. The injectors would handle almost all the mods you could throw at a 351 cu. in. but maybe marginal if going to a stroker like the 408 cu. in.

The Megasquirt ECM has increased the HP by a small margin .The standard fuel and ignition tables on the GT40 are fairly conservative and would handle mild performance modifications. Paul (Gun-Driver) added the better flowing GT40P heads to his GT40 with no problems.

The real HP gains were planned with the engine mods crank, heads, cam etc. The ECM would then have been able to be tuned to gain the most from these mods without damaging the engine.

Depends on what sort of gains you are after PCM put together a great package with the GT40 from the factory.
If you're going through hell, keep going

$100? Would that be the "Reid" method of HP boosting with different HP decals on the engine?

You may want to revise the thread title better indicating what you are seeking, perhaps something like "GT-40 Performance Upgrades Help". Lewy certainly comes to mind as one of our GT-40 Guru's, several others as well.
