Why get so excited about the release of a "new" version?
Will version V7 produce more power.....unlikely.
At the end of the day you can only play with fuelling on N/A engine so much. And the truth is you may get a "headline" bhp figure but the important bit is the area under the curve and how the power is delivered.
Headers will have you running 550-570bhp ( with a header tune).
However, to be making any more you are looking at either a simple NOS install or supercharger install or what likes very interesting is a twin turbo install.
People may disagree.....but I have had mine running on Dyno till early hours of the morning, uploading different maps etc and trying to squeeze that last bhp out of it and you can't feel any difference after it........
