on my way back from work today i went to give it more gas, it reached about 85mph then started struggling and not going anywhere, i looked at the turbo guage and was sitting around 1.3(which is normal) but on the build up to it i was hearing ssssssssssssssssssssssss which i dont normaly, then the boost pressure droped, low boost is fine it goes right by 85mph easily,

 

Any clue to model/year?

sorry its a wrx 2002 bugeye remaped by andy forrest

 

split pipe? hole in intercooler?

 

Possibly a split boost pipe, or do you have dump valve? If so then that maybe faulty

 

how can i check that, ye i have a turbosmart vta on it, but it was working fine during the remap a few weeks ago, ye i know it could be faulty now,

 

Take it off and put the original one back one ifyou have it.

First though check all your boost pipes for splits or if the have come loose

 

cool, will have a look tomorrow then, and swap the bov over if i see no problems with the pipes, i will put the original one back on,
