push the gas pedal to fast and it hesitates and spits and sputters. take of real slow its ok but cant push the pedal past 1/3 or it hesitates again. if i floor it .. then it wont shift out of whatever gear it is in and thisck smoke comes out. this thing bucks like a bronco trying to get going if i push to hard. i just changed out tunes on it to see if it had something to do with the tune and no luck. had it in for service. i upgraded the fuel tank to a 45 gal tank. ran fine but when it reached right under 1/4 tank it would run out of fuel. yes it is reprogrammed to match tank and it is correct. filled up at the station and i had 10 gal in the tank left so it wasnt empty. got it back in the shop and he loosened up the straps on the tank and shimmed it as it was leaning a little to 1 side. he never took it out or dropped the tank at all (this time). after i left there made it about 5 miles and it started acting up like it was starving for fuel (to me anyway). took it back to him he looked on the computer and wot the rail pressure dropes greatly. i am in the process of changing out my fuel filter as i type(on break right now). hopefully that will fix it but im not to confident as i just changed the filter less than 2 mo ago. thinking this might be my fuel rail going out....does this sound like it might be the problem or is there something else to look for. it is driveable if i am easy on the pedal but i am outta ideas (except the fule rail).
any help would be appreciated.
