Hi, I'm new to the forum so excuse if I posted the question in wrong place or something... So the problem is when i'm driving my car and floor it from about 1.8-1.9k rpm, doesn't matter which gear ( i don't do that on 1st gear) the turbo spools up fast and starts pulling good for a 2l 100kw diesel, but at about 2.5-2.8k rpm, there is a sudden drop of power. The car doesn't stop accelerating, but it accelerates way slower than in 2k-2.8k rpm range.. From those rpms (2.5-2.8k rpm) car doesn't accelerate any harder as it actually should do (peak power is obviously at higher rpm than 2.8k) but just pulls with the same power. Fuel, air and oil filters are new. If there was a boost leak i suppose it would have less power through the whole rpm range, not just have abrupt loss of power. The engine doesn't smoke at all. Have anyone came across similar problem? I failed to find similar problems on internet.
