L.A Drag Spot.

So do you guys use CHT and EGT to tune your bikes? Does everyone tune their own bike, or is there someone with talent that people go to for that?
I'm just curious, not looking for any secrets or anything.
I'll stick to 100 foot track, no way I'm going 90mph on a mini bike. You guys have cajones the size of basketballs to be doing that.
