Re: 74mm throttle body problems
I purchased one a year ago and installed it - took half an hour before the idle smoothed out and then it worked fine. But when I accelerated I noticed a difference in the exhaust sound and lost the deep throaty pitch my XF made under full acceleration. I put the stock one back on. Now that I just ordered the Eurocharge kit I am going to throw it back on and hopefully my deep exhaust sound will not be lost.
