Since 19.06.04 I am happy owner of a SAAB 9-3 1.8t (year 2004). Before I drove an MG ZS180. When I bought the Saab, I was unsure what kind of motorization it should get. 150hp or 175hp? My salesman said that I should save the extra charge for the 175hp Saab of 2000EURO, because all the two models were a 2L machine. I should then rather invest 1250EURO in the Hirsch tuning and it would then get out 195hp and the Verein now I ask for some practical experiences from you about the Step1 of Hirsch! Consumption, warranty, reliability, difference to the series, insurance, installation, life, fuel, satisfaction etc.??? Thank you and sorry for the many questions. But I wanted to inform myself before. Greeting Mike
