The early GM MAFs are garbage and the only 165 I have ever tuned I went to $12P MAP based code in.

USA made swap harness I am about to use to replace the Proflow 4s garbage ECU setup I am currently running.

Hiya's,
My original thought was to just use the '7427 to handle it all. Man, that wiring harness price is great. Using a 24x crank and 1x cam sensor distributor is perfect. Sequential spark and fuel would be super neat on a TPI. I like it :)
