    regal stage 2 gsi probs!

    Hi, been regal today for stage 2 on my gsi, come out with 222bhp 296lbft. He said it should be about 260bhp with my mods. The boost just drops at 3500rpm on graph, he said turbo is no good? Is this right? It was reconditioned 3000miles ago just before i bought the car. & its runing lean at 0.9 on the graph & he said it should be about 0.8? Iv not long had the car & its done 15000miles in the last 4 years since regal stage 1 & tue man at regal said the fuel pump gauze is probably full of crud so will need to replace the fuel pump. Does this sound right? Any help would be great, thanks. Also on way home i noticed the dump valve wasnt dumping so pulled over & the vac pipe that goes to the dump valve was off so think when they checked it over before rolling road they knocked it off by accident so was like this during rolling road run, would this of affected the lambda reading because of vac leak? Hope this makes sence. Thanks

    Im from near romford mate. The pipe that came off was on the t piece right near the dump valve. Would this of made a difference to the boost or lambda because the pipe that came off was just sucking in loads of air & doesnt it eventually go to the fpr? How would i know if the turbo is deffinately no good? Is there anyone near me that could help?
