On the way to the Prodrive meet on the weekend, my forester was a little hesitant on full throttle. it felt like the boost was cutting out/in.

It's a 2003 SG5 XT 2.0 with a dealer fitted Prodrive kit.

I've just bought an OBDLink LX, and the BTSSM app, but I don't really know what I'm looking at. Can anyone point to a guide for the various values, and what range they should be within?

Here's a bit of the graph from a short run, if anyone can see any out of place:

Graph looks ok, AFR is where you'd expect on WOT. Might be easier to look at the excel spreadsheet of the data.

Does it throw a CEL?
Is it a harsh cut like a fuel cut?
Boost seems standard level so wouldn't say it's boost creep and boost cut to be honest.

I'd start by looking at the fuel pump. Is it in the original pump?
