After getting some bolt ons done it just seems so weird .......
It just moves up and down even the gauge ...sometimes 50 remaining and sudenly jump up to 60 - 70 remaining ..... why ???....and sometimes the warning light comes on then like few mins later it jump to 40 mile remaining .... i dont know when to fill the gas now ...........><........
what i don now???is it due to the tuning stuff ????
or something wrong with the fuel tank??? should i take it back to dealer but im afraid they will blame on the mods .... help

 

has nothing to do with your mods (unless you been playing with the electronics), sounds more electrical or a problem with the gauge itself
