where can i find one...anyone have a link?
i wish everyone was as knowlegable (sp?) as you, great input.SkaAddict said:It depends...on a bone stock Focus you'll actually screw things up since the computer figures the A/F ratio on the assumption that its drawing a small amount of exhaust back into the intake charge. With modifications and a tune it will eliminate lag, but its questionable if the lag is noticeable. I disabled mine by unplugging the EGR vaccum line from the EGR valve since my DPFE module is dead...before, it would open the valve all the way and after sitting at a light I'd try to launch and it would bog, because I was sucking a bunch of exhaust in that filled the intake manifold while sitting.
When I get an xcalII I'll probably tune the EGR out of the system and then remove it...there's a theory that the engine will be hotter with the EGR turned off; the logic is less oxygen in the intake charge=less fire in the cylinder, which results in a cooler engine, but I haven't overheated since turning off the EGR valve.
