Re: [A/S] Adding power boosting chips to Ford Power Stroke Diesel

["Tom Patterson" <tom@xxxxxxxxxxxxxxxx>]

     I don't have a full answer, but part of it is to protect the engine.  I think that with the chip, I can redline the engine.  Without the chip I cannot, unless I do it in gear coming downhill.  With the chip then, I need to watch the tachometer.
     Addressing other comments, I think that a pyrometer is useful even without a chip.  The engine temperature on my F-250 scarcely budges, whether I am going over a mountain pass pulling a trailer (as with Monarch pass in Colorado), or sitting with extended engine idling in Houston 95 degree temperatures.  This shows that the F-250 has a great engine coolant system, but nonetheless, the exhaust gas temperature will vary from 300 to 900 degrees easily.  Damage can occur above 1250 degrees, but the ideal is 600 for maximum MPG.  Also, the ideal is to cool the engine down to 300 before shutting down.  The gauge helps you measure and manage all of this.
     Meanwhile, back to chip....... I may not need or use the extra power or torque often, but if I do, then I want it, and I don't drag race either.  The MPG pays for the chip anyway (and then some).
     I have not seen anything that indicates that the chip invalidates the warranty.  I have seen such with the exhaust brake, but don't know if this is gospel, or just supposition. 
     For those interested in the Power Stroke diesel, I can recommend getting the Power Stroke Registry.  There is a lot of information and discussion on these various add-ons.  Discussion also, on solutions to other problems that are not  generally known, such as the cavitation issue if coolant additives are not utilized.
