I’ve had the heads ported and polished, delta cams did a 230 grind and I’ve upgraded the springs. Now I need to tune it to get optimum hp. It’s an asphalt round track car. Need any help please.

I think you can use a Link ECU or, a piggy back like Greddy Emanage. Factory ECU cannot be tuned

Somewhere in the anuls of the site there are topics about chipping the stock na ecu. That's the only why you'll get anywhere significant without a difference ecu.
