Now ther are 2 4.5L q45 MOTORS on this site.
you are much braver and younger than I. I left mine in the F50 body!!!!!

My treck to better mpgs was three stepped.
1. using the mpg screen in the car, I started driving 'easier' and got the ecm & tcm to learn the mpg mode.
2. Going to a larger diameter tire 245/50/18 on the stock rims. Lowered my rpms at highway speed to around 1800rpm
3. all the other stuff: scangaugeII, and aero mods(IMPUL body kit, underbelly pans etc)

Check out the links in my signature!

MetroMPG: "Get the MPG gauge - it turns driving into a fuel & money saving game."

First: ScangaugeII

Second: Grille Block

Third: Full underbelly pan

Fourth: rear skirts and 30.4mpg on trip!
