95,717 miles,new oil/filter.Have smoke under hood near/under fill valve,help??

What is your question?

Added a Gforce Chip,working good but now I have smoke,definitely oil,coming up from under the hood. Driver side under fill hole. No fluids on ground at all but oil is most certainly dripping on hot areas and burning before any drips to the ground. Other than the Valve Cover Gasket can you give any even "guess" if not sure advice as to what problem could be? Also oil gauge stays around 30 PSI until I press accelerator then it jumps to 45-50 PSI before leveling off during steady speeds back to around 30.
