I was wondering if underdrive, and power programmer (blue oval) would be something that can be noticed.

Thanks,

Go to www.crownvic.net and read some of the write ups they have.

Usually going to 3.55 gears, a good CAI, and reprogramming will awaken a Vic/GM/TC. But read and research as much as possible before doing anything.
