It's probably not oil. The Dex-Cool can turn into a sludge like oil substance.

What are you using to verify that you have spark knock?

Wow.. that sucks.

Have you pulled the plugs? Any of them have aluminum on them or the ground strap look funny?

If you are regularly low on coolant, it's using it or leaking it.

No signs of leaking it,I have been monitoring that,But it does smoke alot at start up(Greyish White smoke) but it is really humid when I notice it the most,would this make it smoke?
Thanks!

Scott, it is very hard to get oil in the coolant. Like Levi said, it s probably Dexcool sludge. How low is your coolant?

If the tune was spot on and working fine when it left then the tune is not an issue assuming you haven't changed/added anything to the intake/motor/exhaust tract to alter A/F ratios.

Check your plugs and wires (all of them, not just the first two or three plugs).
Are there any DIC codes that Autotap picked up?

Also, how much KR are you getting at WOT? It could be false knock. Put some octane booster in there, or some 100 octane gas and re-tap it, if it doesn't disappear then it's false knock.

Chris it isnt to low ,but it has been lower than in the past when it is cold the coolant is lower than the spring looking thing under the cap.Levi ,I checked all of the plugs and the thing that gets me is that they look fine,Now on the other hand I will be getting new wires soon.I am not getting any codes,but I am getting the full KR my tuner has in it,4 degree's.I think it could be False Knock also,But this thing was feeling very wierd on my way up north.My car is going in to APE(Chris's place)In a week to be put on the dyno(This I do want to make sure every thing is good)I have not played with any A/F or Timing with my HP Tuner just starting issues with the 400 800 in the VE Table and the IAC and this car starts awesome now ,Thanks to some of the guys on the Tuning board hereThe car does feel low on power and I just want to make sure all is well,Could my TR6 spark plugs gapped @ .035 be a problem?
Thanks!
Scott
