On the Lightning page they are setting their TPS's as close to .99 as possible. I checked mine and it was .95 so I bumped it up to .98. I notice now in my Chilton book that they recommend it be set in the area of .90 but no specific reading. Are our 5.4's set the same as the Lightning guys or do our like a lower setting? Thanks. I posted "TPS adjustment tips" on the Lightning page if anybody cares.

 

HI!... Common practise is to set your TPS at about 0.98-0.99 volts. I've had mine set at 0.98 for 5 years now with no problems. The factory had mine set at 0.86 volts if I remember correctly. After the adjustment, throttle responce was much improved. I have a regular N/A 5.4 by the way.

 

Thanks Neal.
