Advance timing

When tuning for the best timing on the street can I have the stft,ltft,dfco on? Would it affect in anyway? Also the tables for open loop can they be set up back to stock values or just Leave everything in 1.00 till am done with timing? Reason I ask is because am in the track testing and the weather is kind of hot and don't want to get different results once I settle timing somewhere and turn everything back on is all over the place. Thanks for the help in advance
