okay so i know what to do with the fuel plate but which fuel plate is best for my truck?
i have a 96 auto which one would be the best? overall i want more pwer but i still want good MPG, how much if any would it hurt my MPG?

 

First question is your truck stock?I have a #10 plate on my truck and it's moved forward a little.But mine isn't stock anymore.And averaging around 16/18mpg city,22/24 freeway.But overall i'm really happy with the #10 plate on my truck.

 

yes so far my truck is stock ill be getting gauges soon

 

Good,the first thing i had put on was guages.Then you could move your stock fuel plate forward a little and see what that does to your e.g.t.'s.Then go from there.

 

iirc, i herd that a 10 plate will cook a stock tranny? i might be wrong tho. when i had my dodge i was going to do that but got told otherwise.
