Hi there all how are we all today ...

I have a 2000 classic shape turbo and today i went to the local subaru garage to get my new 4" backbox fitted but when i picked it up tonite . The cars turbo wont boost it sounds like its spooling ok up to 3200 rpm and when the turbo normally would kick in it just die's (no turbo) the dump valve stops venting and it feels just like a normally aspirated car There are no cel codes and its just had a major service 2 weeks ago by the same garage

Any help guys would be great ..

 

Now some times on and off the car Drives like there is no turbo at all it just drives with no turbo spool and increase in boost or anything ?? Could the new backbox cause such a problem ??

 

sounds like it is in limp home mode tbh. Call the garage that fitted the BB & if not to far go back & ask them to plug in the select monitor to check for the problem

 

Do you think reseting the ecu will help ?? and the car was totally fine this morning thats whats confusing me as i didnt think a backbox would affect the car in this way
