[niddydsm]

Alright so my dsm has been sittin for about 5 months I just got back in town and wanted to take it for a warm up cruise when I got the car started I went to take off and the car drove good untill 3k rpm I have a blow through system and my turbo is blown so I unplugged the turbo so there wouldn't be a chance of a blade breakin and going into the engine. When tthe car idles I can't rev pass 3k and when it drives it don't either I had my brother rev so I could check the exhaust and when it reaches 3k it spits black smoke but don't back fire please help
