I logged my car because it felt kinda slower than normal . I'm Cobb stage 1+ fmic aggressive . I noticed that I have some really bad timing corrections in 4 of my cylinders . Is there any way to determine if my plugs are old or if I just have bad gas . The plugs have 30k on them and tunes since 26

Are you throwing codes? How bad are the timing corrections? Can you upload the log?

There are definitely more corrections than what i like to see. If the plugs have 30k i'd go ahead and change them anyway and as far as bad gas goes it's possible. Try a different station next fill-up or put in a bottle of NOS off road octane booster and see if it helps.
