hey guys, i set the timing about 15* and engine seems to like it, great throttle response and quick revving, problem at WOT still but i would say it's minor so, i went further and installed an A/F ratio with analogic gauge, it's made by Fuelairspark or something like that, anyway, it says 14:1 at WOT wich is too lean i guess and even leaner at idle, it's usually close to 15, the richer value i've seen is 13ish but very rarely.

I spoke with the tech guys at Howell EFI , and he agreed with me to increase fuel pressure to achieve a richer mixture in the all RPM range, i don't know if is a good idea try to modify the TB internal pressure regulator or just put an external one with a gauge, anyone who worked on the Throttle body?
