Hi Guys,
Sorry in advance if this has been covered but I could not find a proper answer for myself.
I've recently had the GIAC stage 1 tune and very happy with the power. However, every now and then in 2-3 gear I can hear the engine pining on WOT (3500rpm-4000rpm). I thought it could be a heak soak issue like everyone has mention in some cases, however I have let the engine settle down on a cool weather day and still not helping. What makes it more difficult is the pinging only occurs every now and then.
I've done the below to help fix the issue but has not worked
-Fresh batch of fuel BP 98
-injector cleaner
-As mention below plumb back the BOV
Car is quite standard beside MODS below
-PF160
-Drop in pod filter
-Turbosmart dual port BOV (which I have now put back to plumb back just incase that could be the issue as there was a thread talking about pining issues due atmospheric bov) Still pinging however

I just wanted to know if anyone with a GIAC stage 1 tune is having the same issue and what other problem solving I can do that wont cost me money like the below. Could it be just be the AIR/FUEL tune in the GIAC tune?
temp sensor?
Plugs? maybe go one colder? NGK BKR7E
Any feedback would be much appreciate.
