Got the car re-tuned over the weekend. I did a before run which was 295/245. After the Z1 plenum I was at 305/254 this was within an hour of each other. It was a rainy damp day so that might be why I was at less power than my previous run a few months back. I will have the dyno sheet up as soon as I get it from John. I will be going back again very soon for another re-tune due to unforeseen circumstances.
In all I can say that I feel a lot more power in the mid range and all around. I will give a more detailed review as soon as I get the car tuned one more time.
