Old South,

Was doing a search for ALDA information and came upon your statement re: disconnecting the EGR on your 603 engine ... I think your engine is much the same as the one in my 91 350 SDL, right?

Well, it seems like my performance is down ... so, I was cleaning vacuum lines, etc ... I had previously removed intake and cleaned out 10 years of crud associated (I think) with the confluence of EGR heat into the intake where the valve cover recirc entered ... looked like the EGR had been cooking off the oil fumes ... figured this may have been related to the momentary hesitation and puff of brown smoke on occasion, during extended highway driving.

Can you give me more info re: the EGR disconnect? I plugged mine, so ... if this causes sensing to occur that reduces the boost output, it would seem logical this is my problem.

Thanks!
