i have my evo tuned all i have is uicp,turbo backe exhaust,fmic boost pill removed.. been having some issues ever since the tune.. my other tune seemed fine,but after the new tune my car is yup and down on powe5r.. i was tiold looks like it is not hitting target boost all the time.. i was told for a fee i could have the car rechecked and retuned.. not sure why there is a charge since it has not been right since.. please give me some thoughts on what or how i can check myself..
