Compression Ratio

Do i have to get new pistons in order to increase my compression ratio? I have searched but found nothing. Or is it just in the ECU. Thanks.

Either that or mill your heads. Compression ratio is based on crank stroke, gasket thickness, deck height, piston type (pop-up, flat or dished) and cylinder head volume.

Although milling the head is easier, domed pistons are the proper (and more expensive) way to do it.
