1) Please watch the foul language - this is a 'family friendly' forum.
2) Please describe more about your Supra's configuration. For example:
....a) Was it an Mkiv TT before you put in an Aristo engine?
....b) What device are you controlling the boost?
....c) Which electronic device are you using to eliminate fuel cut? etc.
3) As warmkop asked, how much boost are you running?
4) Have you checked for boost/vacuum leaks?
