Question over boosting

hi not long got my myoo turbo 2000 back on the road again after alot of turbo probs . ive put a standard td04 as the original went . along with a full 3 inch exhaust . the problem i have is when in 4th and 5th on the motorway its over boosting . ie 1.4 bar and the turbo feels like it coming on and off . i put the pipe with the resister pill on the turbo side of the t piece , i think thats the right place . is there any onter resisters in the pipes to the boost solinoid on this model .

Then decat is the cause and remap is the solution. Merry Christmas to you.

You dont need a fuel pump, though if you have mega miles on your car it is worth changing either to another standard subaru one (they are up to the job and seem to outlast even some of the uprated ones ) or something like a walbro.
If your going for a panel filter also, ensure its of a dry type (STI/K&N or Green) as the oil will kill the maf and these dont like induction kits (vibration kills the maf sensors).
