Ok.... i have a blacktop SR! it was running fine when i go it! but now! whenever i just punch the car there's a sound coming from where the turbo is... im not sure what it is....but it sounds like a GRINDING sound from the turbo side! my uncle said it could be the Airflow MAF sensor... he's owned at least 6 240's the past 4 years. but if i drive it at regular speed without punching it, it sounds fine. just wanna double check on this! any HELP would be fine! thank you

there are no major mods on it just stock SR t25 turbo, and yeah! it doesn't make no noise when driving normally. just when being punched.
