i have recently just had forgies put in, big end bearings and all my gasgets replaced. Now I took it easy for around 1200k's running standard boost and now I have some issues. I wound the boost up to 9psi just for starters and was driving it around a bit and was giving it little hits and I found that it was spooling up but I wasn't getting any power. At first I thought it was lag as I have a front mount and the piping is quite long, but then as I got to around 5k rpm I still wasn't getting full power. Can somone please shed some light on this for me cause it's getting awfully dark around me. This is really disheartening.
Also, Compression is fine.
Could it be the way we have set up all the little things?
