When i bought it ,i asked specifically if it was 'chip tuned' in any way. He said its not at all

for the past month i had some problems with my car, sudden moments when it doesnt go past 2500 rpm. if it stop and start the engine again it comes back to normal. took the car to a old friend thats a pretty good mechanic and he said that he pulled out every single sensor to see if it appears in the dash..it did till he unplugged the turbo sensor one..that one didnt appear, any ideas why it doesnt appear? (sorry for bad english or bad explaining)
