To be honest i may be jumping to conclusions.
A couple of replies i had about a recent post of mine suggested valve float or possibly a worn cam but the engine is only 3k old, i run the cam in properly. I did notice that my original valve springs were a little tougher than my new piper springs, obviousley due to less material
Basicaly my car is loosing power between 5 and 6 thou.
What do you mean by losing power between 5-6k? Is it noticeably running out of puff? It could simply be all done by then. What Turbo is it?
Is it Misfiring?
It could be lifters. Thats quite likely.
