as far as anything I can do to him , its a very good friend of mine , but his mechanic installed p28 and ignition and fuel tables are not the same , so the car was running not quite so well , so I decide it to help him to make his car run better, I chipped his ecu and installed p30 with p2p tables , and runs lot better, we installed the wideband too and seems to be better , before was too lean , but I think that car should be running better than what it is now , he is using a6 intake manifold , and he is changing that this weekend , he is installing y8
aparently the mechanic shaved the block and the head a little bit just to have nice faces . and he is using cometic head gasket
