I can said that it may give me more mpg gain. I didn't have to step the gas to half and the truck was already moving faster as I have been steeping it pass the half way to the gas pedal... I think this is a good tweak to the ECM? The performance is very noticeable after the install...

But again I think it can depend or vary by truck...

That gauge will do nothing for performance, fuel economy or anything of the sort. It sounds like you have messed something up with the install.

All that gauge dose is makes a little light display to distract you wile driving that's about how useful they are.

If it started running bad when you disconnected it I bet the wiring is damaged from your install and taking it out broke the connection making the truck run bad.
