hi guys, got a problem! i have a 2004 wrx and it has a fault. every now and then when driving ill put my foot down and it will not go, when i look at the boost gauge its only showing 0.5 bar. i can turn the ignition off restart the engine and boost will be back up to normal. this problem is starting to happen quite often now so i thought it was time to ask for help. im running standard apart from ppp. i do not get an engine warning light on when fault occurs.

used to have this on my sti. It happened if i held it for a few seconds at no boost. i.e. the guage on zero.Then booted it in the high gears. Had loads of different things checked out and couldnt cure it, Then had the ecu re-flashed 18 months ago and havent had a problem since

not sorted yet, cleaned boost solenoid problem no better. i do find that when the fault occurs if i turn the ignition off then back on it usually clears it.

Hi tony didn't know you had this problem too, mine's suffering with it also.

Turbotits what do you mean in having the ecu re-flashed.

Also didn't have this problem b4 i fitted the PPP. Coincidence??????

After many people looking at it. Although it could been seen to be doing it on computers,boost guage etc. No one new why or what was doing it.

I had it re-mapped (ecutek) and still had the same problem. I then had it mapped again where i believe the base map was totally renewed and this cured the problem

chris its funny you should mention the ppp because my wrx is fitted with this too!

Hi all it all started when i had it mapped at scooby clinic thay say i need a new turbo, has any one else been to clinic?

Its drive by emmissions mode, std feature on all these ecu's, even more prevalent on a Jecs, needs a map switch rom using set up with the main boost maps a certain way round, that will eliminate. JDM code doesn't seem to have it mind but that won't work in Eurospec cars.
