noob valve spring question

If the mechanicals are straightened out, the first thing I would do is change out the ECU. The silver box with the heat sink. Make sure all of the grounds are good and the motor is grounded to the frame. I always add a braided strap.

That was one of the first things I tried. I swapped it with the one from my slant 6 car. Made no difference in either vehicle. I don't know where the 225 shifts at since there's no tach in that car, but I'm guessing it probably gets up around 4K at full throttle in first and second.
