Oh sn@p! :banghead

Well here is a comparison dyno between the pre and post spark plug change.
Doesn't look like I recorded the cleanest run due to the power curve at 5100rpm but it shows a noticeable improvement using the same mild tune.

I'll check the plugs from time-to-time and change to the ITV20 if they start fouling again.

Here are the logs, but I only recorded the 3rd gear pull so not sure if these will show much.

That's ok, I just wanted to see if the horrendous ignition retard from the previous log went away. And it kind of did, pretty much.
