The more I look into these things the more questions I come up with.
I have a early 1999 F250 crew cab 7.3 liter auto trans. 4x4 that I want to put a chip in. She's a virgin... I do have gauges and exhaust done so.
Should I be putting a aftermarket valve body in the transmission?
The order form on PHP web site asks for idle rpm. At this point it is stock aren't they all about the same?
It also askes if it is intercooled. Again it is stock. yes it intercooled but not after market.
I see on their web site that they have both Daily driver and Perfomance calibrations but on the drop down on the form it is listed as performance. ie 80hp performance. DD is not listed as a choice.
Will the MPG display be even close after the chip is installed?
And last what order should I place the Calibrations in?
Stock
65hp tow
80hp daily drive (listed as performance on the drop down)
100hp performance or should I go with 120hp. Will the seat O pants meter know the differance.
Whisper Mode
Fuel sipper
Let me know what you all think and what changes I should make.
Peace
