its deff your coil packs i had the same problem when my car boosted it fell flat on its face through that rpm range....and it drove fine if i didnt boost
do all five you might as well
very easy and quick took me about 45 min for all 5. they are cheap too on tasca
i wasted a lot of money listing to people tell me it had to deal with my MAF and waste gate........R's eat up coil packs as a result of the harsh conditions produced by the turbo
