That's a great write up on your performance header, Mark. Did I mention they are also extremely sexy?

i'm sorry mark, i've forgotten what your sugestion was with your header and fuel injection. saw that with carbs it leaned the engine out but with the o2 sensor in the header will it lean out the fuel injection bad

On a FI system you would need to check fuel mixture through the rpm range. The O2 sensor doesn't affect the Fiat system at speed. The injector pulse rate is set by rpm and air volume.
I haven't installed a system on an FI car myself, so I haven't had the chance to test fuel mixture results. The AFM may have to be tweaked if the air bypass on the AFM isn't enough adjustment.
