If it goes from like 14-17 down to below 10, it's no beuno. Best is to compare other logs of your own car to see where you are typically
Yeah, I just didn't want to recommend settings that George wouldn't recommend. I think Diggs' advice to lower boost was spot on in this case. I've been running an 18 PSI tune for Winter with a less steep boost curve, and then I run a 21 PSI tune for Summer using (both with FOL 70). It's been great and stable and I haven't been messing with it much. For me, I find this to be a nice trade-off between performance and longevity, but I realize others want to keep pushing things as far as they can.

Guys I am thankfull for your help and your advise.
In my case I don't intend to push to the limit of the engine but I have to cope with trims not going higher than 36/37 (even if running lean). And only because of this I need to go little higher than FOL 70. I ran 70 with is12 already and now with the bigger turbo I just want a little more to make it worth it. I don't want to try boosting up to upper 20s but just a little over 20 with tapering to 16/17. That's it. But that is not possible at the moment even with FOL80. My boost needs to drop rapidly after 4500 otherwise afr rises.
