if you tune a ST to RS speck, it doesn't make it an RS does it.
Problem being Rich the ST engines has too many fundamental difference to ever make it an RS. For one the block and secondily the turbo.
The 'standard' RS and the '500' use the same engine and turbo etc however the 500 has the mountune upgrades from the factory...
