That was an original plan mate and the greys were a short term solution. I was expecting less power really from them really. I was also learning about the ecu side of things at the time and it seemed to be the cheaper option.
I don't see how on paper it develops the power it does, esp regards the grey's limits as mentioned here. btw I also took out a 380 (Interpro figure) bhp cossie today with quite some margin - big difference... his words not mine.
Does this chat help at all rst-g???
