The results were all over the place.
I made 274rwkW on the same dyno with Ben's tuning, just a couple of months ago on 16psi.
Couldn't get more than 262rwkW yesterday and I upped the boost to 17psi.
Also checked the graphs, air temp sensor was fine when I ran in the morning, 24 degrees on the 274rwkW run, 27 on the 262rwkW run.
Was running on 10,000km old plugs, but still. 12rwkW's?!?!
Maybe I got slight wheelspin or something in the midrange cause the car wasn't strapped down like it was when it was being tuned?
meh. It's all good.
Great day all in all. Hurray for Abobob and Ben.
