Hello new to the forum
had my 2010 f6 for about 3 years now
I put a 4 inch ultrex exhaust on came up with the p1227 which told me the wastegate flapper was stuck open
so I bought a new wastegate with a 12PSI spring just wondering if that would make it run lean im obviously going to get a tune I just need to know if it is less than ideal to be driving the car with these changes
Cheers
