Ok guys

I have a PS F250 and I have two questions.

1. At slow acceralation when the tranny is trying to shift(around 2 to 3K PRM) the engine surges about 5 to 8 times before the shift is complete. [with or without a load] what could be causing this? and how could this be fixed. The truck is new to me and has 75K plus I was told not used for towing prior to my acqusition.

2. Why would my fuel gage start showing full everytime I start the truck. only new things in the works is JUICE with ATTITUDE install and 4inch exhaust.

Did the surging start after installing the Edge? Have you tried it on any different settings? Is the trans fluid clean and full? Is the engine oil in good shape and at the full mark? Does the fuel gauge stay on full or does it go to full then back down to the actual level?
