Jurgen Biggelaar Posted February 15, 2010 Report Share Posted February 15, 2010 Hi Stephen. This is one of those times that more info would be good. I am assuming at this stage you have a GEN 1 SW20 Turbo. There are a few paths we could go down, but are there anymore clues? Knowing if you are rich/lean at this point would help a lot... Do you have an AFR reading hooked up at all? Are there miss fires, is it BANG ON 4100RPM every time. Does the power fall away in a snap, or over a few seconds? Anything you think may help...
