I have a 04 wrx .25 over on cylinders, vf34, perrin/ic ,sti pinks, exhaust,cobb access port, had engine rebuilt prob. 15k ago. loss of engine power and turbo not spooling over 8psi except sometimes when cold, exst temp runs hotter than normal it seems just regular driving almost 14. thimking maybe a bad hose but why only sometimes will it spool and why no power from the engine? Not showing any codes. Please any advice is better than none..

Sounds like your ECU has pulled out a lot of timing and then dropped boost. This generally happens when knock occurs or if the ECU is picking up noise that it interprets as knock. Have you talked to your engine builder and/or tuner?
