I see ~270 with the stock turbo, although I am killing it.

His peak loads in 4th are (iirc I'm not near my computer) [email protected] then 1.985 till 4.5k then it drops sharply and tapers off to 1.3@redline.

Good points, but wgdc wasn't at 100% in the last lot of logs and that load doesn't climb in a straight line or hit target till 3700rpm which would indicate a boost leak. I didn't touch the higher up loads or timing in the last revision so it's strange that all of a sudden these issues have appeared ...

Just noticed the way the load climbs as well, it should rocket straight up. I'm saying defo boost leak.

There is a lot of random high KR in the logs which wasnt there before and every time its at a different rpm/load point. Wgdc is also pegged at 100% and for some reason the maf cal has drifted off, I think you may have a boost leak and are in need of some itv22 spark plugs.

It's strange because I have the highest loads set for 4th gear. As I said, I'll take a look later.

From what I understand (not a lot basically). If the wgdc is higher than required you can get load spikes, if it is lower the only danger is not meeting load targets. Seeing as the tunes are "one size fits all" then they have to be conservative

As long as you're hitting load targets don't worry about the throttle position, the ecu uses throttle closing to control load

That's bad luck, but surely you have an idea of where you were with the tune do it shouldn't take that long to get back to where it was before?
I email myself a copy every few revisions to avoid this.

All you can do is follow the numbers, if they're off that far it'll probably take you a few revisions just to get the trims acceptable.
