hey guys needs some help. when im in 4th gear and roll on the throttle making my way to full throttle(to prevent downshifting) my turbo sounds like it all of a sudden takes off and spools like crazy around 80 mph once she really gets going. it will also does the same in 3rd with tow/haul on under the same type of acceleration. does anyone know what this might be? thanks again
