hi all, bought my first impreza about a month ago and has been a massive headache ever since, its a 95 uk turbo 2000 it has a td05 turbo, manual aftermarket boost controller and was told it is running 1.1 bar of boost, however not long after i got it i lost boost and have not yet located a leak, i found that the factory boost controller had bean bypassed and not knowing much about subarus and modding them i plumbed it back in how it was ment to be, i took it out and 3,500 revs come with a massive backfire and i nearly went through the windscreen, i put the aftermarket unit back on as was when i first got it but the car still has the problem now i all gears jerks and backfires, does anyone have any idea what could have been damaged to cause this??? and possibe ways to fix it
cheers :)
