Guess this just proves there is something to the "Italian Tuneup." I for one will continue to research this phenomenon by frequently putting the pedal to the metal. All in the name of research of course.
I did put auto-rx in my old Firebird twice, but I don't believe I ever did race with it in there. I do believe it cleaned out that engine very well and helped it run quicker. It was a very strong running LT1, it made 265rwhp with a catback as it's only mod. And it ran 13.74 at 100mph in 100% stock trim, which is extremely quick for an LT1.
PAtman , i dont know if your timing your runs but it may be that your "use" to the takeoff and the "excitement" kinda fades down do to de-sensistivy?quote:

It might have something to do with blowing out some of the carbon perhaps?
Nope, every run gives you a timeslip, so I've noticed the trend with a lot of my vehicles in the past that the later runs are quicker ETs with a higher mph, even though the weather usually gets warmer as the day goes on. I notice this happens more if I had not driven that car hard for a few days before racing. I do try to do a lot of full throttle runs on the way to the dragstrip whenever possible though and this seems to help.quote:

What exactly is the ECU and how does this work?
It's the engine computer and controls the fuel injection, air flow, etc in EFI cars. It also controls electronic auto transmissions, climtae control a/c, and a few other systems in modern cars.
