I bought it off of a member on here not had any known problems with it and not got any issues, needed one because I put the td05 on, would have just liked to have known which one it is..

his mailbox is full.
Seems to run nicely though but without a afr you cant quite tell.
Is there a guage for this that can be purchased, the car came with a cheap boost gauge that does need changing eventually boosts to just over 10 psi then drops off slightly but doesnt calibrate itself to 0 exactly.

To check the AFR's properly you need a wideband unit or a spin on a RR.
It doesn't sound like it's running any more than stock with those figures.
1C, 3B, V9, V5 , V9, 4B, WRX WAGONS-
10.55PSI (0.7BAR) DROPPING TO 6.84PSI (0.5BAR)
STARTS TO DROP @ 5000RPM–
FUEL CUT 13.79PSI (0.95BAR).
Not to sure on this one, so maybe you or someone can confirm.
As you are running the TD05, can you not rejoin the J1 and run the OE map. If it is a Z4 then it will give you better gains than the 'chip'.
edit; I've got one of these fitted, not exact, but once you know you AFR's are good and you get use to how this one acts then it's good enough to keep an eye out for any changes.

Where is the j1 though
So your running a WRX Wagon with a TD05 fitted?

With the yellow connectors towards you, you have the vertical piece of board, look just to the right of it, on the board you will see written J1 and the resistor should be cut.
It could also of been totally removed, in which case you will need to be handy with an iron

Looking at the pic ive got it seems as though the j1 is no longer there could i solder one on from my original ecu and would this then run it back as a standard ecu..

Some people run a wire from each point to a switch so they can run 2 maps. So the resistor is not really important.
