Halli Hello Hallöle ! I would like to let my Saab 9-5 Aero tune. At Hirsch I get a package from 250 to 280 HP with new exhaust, charge air cooler and air filter for a total of CHF 6’500 (!). The company Motorpower in Switzerland now offers me a pure chip tuning without the additional parts for of course much less investment sum. Does anyone already have experience with the company Motorpower ? I am not sure if this can also have a serious hand and foot, if you don’t have it Thank you for your input. Helvetic Greetings Filet
