Right, i've been reading your post history.
Firstly it would of made it easier if you had stuck with your original thread instead of starting new ones, as this keeps all the info in one place. For instance Prodriverules would know what car you have and that you say it is standard. (it's a MY99 UK2000 Ryan)
First thing you need to do is a full ECU reset as per the link you where given by Musso iirc. As when you wasted your time doing the stupid 'unplug the MAF and see if it still runs test' you will have caused the ECU to 'store' the MAF fault and it may not be faulty.(just unplugged
by you)
A faulty/missing Lambda will cause you problems too. As when the car is running off boost the ECU is in 'open loop' and requires a Lambda to monitor/correct fuelling. When running on boost the ECU switches to 'closed loop' and does not rely on the Lambda for fuelling. Hence it goes well under load but runs rough otherwise.
Your Lambda will/should be in one of two locations, in the down pipe or in the drivers side header. Who ever told you it is not needed due to it being decatted, was, talking bollox mate.

Cheers for you help b13bat. Ive found the lambda sensor but is there just 1 of them or is there 2 i have to change.? Also my car is a 1999 subaru impreza 2000 uk totally standard apart from the de-cat exhaust.

IIRC the lambda it has 3 wires, yes??
If so, you need the LS02 from http://www.lambdasensor.com/main/muniversal.htm
Don't be tempted by the cheap universal one on ebay, they last about an hour.
Any thing for an easy life. I'm just pleased he only had 28.
