Is it all in my Head?

Installed my 93 tune last wk. The thing was reading to take off by itself. It chirped the tires between gears. Now it does not seem to be as aggressive anymore. Is it in my head or could something have caused this?

It's the learning strategy. Pull the negative battery terminal and drive it like a bat out of hell. Once you start slowing down it's going to start changing the tuning to adapt for it.

Or reload your tune every time you fill up.
