yellow mirage is Jerry aka lancerman.
Who is a very knowledgable person in the workings of the ICE.
He builds engines, trannys and is a good tuner.

Al is also a very knowlegable person in how the ICE works and how to make it go. I also agree with him. A ICE is a ICE. The electronics or lack there of is a different story and thats where some people specialize in certain brands when it comes to the tunning. But anyone who knows there way around a engine, especialy any modern one can figure all that out with out to much difficulty.

I would consider myself one with good working knowledge of the ICE and how it works as well as a good tunner that specialises in Mitsubishis but I still lack in the over all knowledge that the likes of Jerry or Al and a few other here have.
