as above pulled onto the motorway and procceded to accelarate but as it got to about 4000rpm it seemed to lose a conciderable amount of power and this was followed by a strange hissing noise(not the same as when it comes on boost). the motor in question is a P1.

any ideas as to why?????????

thanks trb

Check the intercooler to Turbo and i/c to throttle body hoses...I had the very same problem with a WRX previously and found it to be a loose i/c to turbo hose. Check the jubilee clips etc.

turbo to intercooler and intercooler the throttle body are he usual suspect, tighten the clips up with a screwdriver and see if it helps.

thanks i have just refitted the i/c to throttle pipe back on because the j/clip had slipped completely off!

thanks again

Glad you sorted it mate

If you are running above standard boost it may be worth changing the standard TMIC to Throttle body Pipe for a Samco/Silicon replacement as it will happen again as the originals weaken under boost causing the jubilee clips to slip off as they balloon
