I think VE tables are not used to tune the Gen-IV motors.

I stand corrected; especially on a 420 stroker.

Check engine light came on last night (200ish miles driven after install) w/ code p1075...air/fuel management. I checked the O2 wires thinking they may have burned on the collectors but, they look fine and have plenty of clearance.

I'm glad I'm not a tuner, there is just too much to keep up with. My '02 OS doesn't even list p1075. There is nothing between p0804 and p1106 in my list.

No P1075 DTC listed in Mitchell. P1175 is listed, however.

Attached is the daignostic info from Mitchell. Good luck!
