I bought my 2008 evo x gsr last year in may with 45000 miles, its been driving really good till last couple weeks. It feels like im lacking in power or turbo but something is not right. Taking off smoth from a stand point on first gear my rpm jump dramatically to 5000 rpms with barely gasing it, then the rpms drop to like 2500 to 3000 rpm once i start punching it from there at 3800 rpms i get my full power and the car takes off like its on crack. and this happens with every gear the rpms fluctuate and getting me full power at 3800 rpms. Not sure what could caused this. My guess could be the turbo going out or the transmission........maybe not sure! any feed back would be great thanks!
