Right before I went for a tune I filled the tank with 50/50. I never really went into boost on the way to the shop so I cannot say whether or not that was the case. However he was able to fine tune my base map with out any issue.
I read through this
http://www.aquamist.co.uk/vbulletin/...ead.php?t=2091 thread and it seems like it could be a threshold issue?
When he started to turn up the boost and dial in the tune for the methanol thats when the failsafe started to kick in.
I tried adjusting the FS-DL fully clockwise last night with no change.
