hi
I have a Nissan skyline r33 with a lot of work done on it. It should be able to make around 360rwkw but I have a problem. My AFM is a q45 witch maxed out at 280rwkw at 13psi. I have found out since then that you can get q45's with a bar cods ending in P60 or P61. I have the P60 but I have been told that the P61 is only about 10% better. Can any one help me in finding an AFM that will work for me with the power I will be making?
