thats what my frieds think but we checked out and cant find a leak i do know for a fact that when this does this the wastgate is opening becouse u can hear it coming from the wastegate could there be a problem with the wastegate actuator one of my friends thinks its the computer but i dont know and i didnt know if i just need a wideband to tune the car i bought this car and somethings were taken off before i found the car and bought it but i cant get ahold of the origanal owner i did find him through a dealership they gave him my number and he never called be back i just dont know what to do

If it's an external wastegate then it has nothing to do with the computer. I would do a boost leak test with an actual tester...which you can make yourself out of a coupler, piece of plastic and a tire valve. Just make sure you use your own compressor not one of those ones at a gas station.

my friend and i looked at at my car and he showed me how you turn the key over 3 times to dispalay codes it had the 633 with he belives that the previous owner took off the tuning program he had on with a ecu reflash witch makes since why it builds to 10 pounds good and then it falls on its face if the computer is set back to stock could it be runnig lean in high boost causing it it to cut out any body have any ideas
