Hey guys, I thought about putting this on the e36 forum..but I decided to put it here since its more on the racing side....I changed my m52 manifold into the m50 manifold....now... it seems like the car pulls better in the higher rpm..but on thrid gear it feels like theres a dead spot at about 4,500 to 5,000 rpm.. the rpm climbs pretty fast but up to that point it'll stay there and lagg alittle until it passes over that then it'll start to climb again.. would this be fuel shortage or some kind of air restriction? I cant figure it out...anyone has a clue?
