What benefits would I get by changing the ecu on a 89 gt 5 speed? Is there any certain 1 that I need? Does it give more power on top end?

To be honest, I'd suggest searching the 1st gen section of the forum for XR4TI...you'll also find some info in the sticky regarding Escort Performance at the top of this section.
