I just bought a 1999 Ford F550 crewcab dually custom by Eclipse. I am looking at adding the AFE Diesel Elite Pro DRY S Momentum HD Intake System; Ford Diesel Trucks 99.5-03 V8-7.3L (td) 51-73002-E cold air kit, upgrading to a 4 inch exhaust and adding the TS PERFORMANCE SWITCHABLE 6 POSITION CHIP. This chip has high idle, 50hp, 75hp, 100hp, 140hp and valet poistions. I am also adding a EGT gauge, transmission temp gauge and a boost gauge.

What do you folks this of these add-ons? I will not be using the 140hp position or most likely not even the 100hp position. 75hp is the one I will most likely run it on most of the time as I am towing a 18,000 + trailer. The engine is in awesome shape. Serviced meticulously by the previous owner who passed away. Anyway. Kick me back opinions good or bad if you have tried any or all of these items.

 

Moved to the 7.3 section. I think they will be more helpful here.
