Going to try this post here first, here's the scoop, 1997 7.5, 5spd, s/d system. With my scanner hooked up driving @ wot the pcm goes into closed loop, you can actually feel the power loss. live data shows stft subtracting fuel and injector pulse dropping to 16.2 ms from 21ms.
From what I could understand is that it is some type of emissions strategy from the pcm, has any one else run into this and how do you over ride it.
(Thats the readers digest version any input would be greatly appreciated)
Thanks, Dom
