if anyone is near oak grove missouri DO NOT take your diesel to Midwest Diesel Performance! They will rip you off and will not complete your truck until you bring a lawyer into the situation. they had my brothers truck for 3 and a half almost 4 months to replace the number 6 piston and sleeve, all 6 injectors, and the clutch. we called them every day and they kept sayin they were waitin on parts and then once we started taking legal actions all the parts somehow randomly appeared out of thin air. he finally got his truck back yesterday and we started looking things over and they didnt even do anything wit the clutch and they disconnected his pyrometer so he couldnt tell how hot stuff was gettin on the 1 HOUR ride home and then we realized that they did not put any engine coolant in it, not a drop. when my brother told them he was getting a lawyer they said that they have been sued befor and it didnt do any good so bring it on. please take this as a warning, this is not a joke. jus tryin to help everyone out
