Weird noise

[MSPHXC]

what are you boosting?
what are you using to control timing for this higher boost?
are you using a general map on the a/f controller?
or did you get the controller retuned for the higher boost level?
do you have a wideband or do you know what a/f ratios you are at?

Im supposed to be boosting 10. But it sometimes spikes up to 12. I had the shop tune the split second a/f for me so im not sure what ratios and stuff. Im prob. either gonna mess with the a/f computer or just take it back to the shop end of this week.
