Moin! A well-known one of me drives calibra, 2L 8v 115ps, believe 92 or 93 year of construction, knows net exactly. Has a N20/Nos system been installed a few days ago, which according to Tuner should bring ~50ps. But nothing there, the plant does not bring anything at all. Something can not be right. He noticed that it smells quite nice after the gas, if it is used, whether the line is not completely dense? Well, at least it did not suffice in 1on1 against a 300kg heavier 25ps stronger car, that says already everything. my theories: -Leck in the line: There is no or only hardly any nitrous oxide in the intake tract. -Lambdasonde broken: would then not know that there is more acid, with which one can burn more sprite… -Einspritznoses too weakly would be great if you could help there perhaps! btw. what diagnosis has the calibra randomly from this year?
