sounds like you could be running rich. I know when I went to stage 3 stock turbo tune my car started eating gas. I average around 24mpg combined on the straight freeway I do much better. Though get in any in town driving and fuel just gets sucked down. I don’t drive with the lightest of foots either though. lol It will be interesting to see what happens after the s280 goes and I am dyno tuned . That happens on Nov10-11.

Would there be any reason to think the HPFP tappet would be worn out at my mileage? I have been tuned for 30,000 miles and my hybrid turbo has about 45k miles.

I've wondered that same thing with my car. I don't take it easy on it though and get about 25mpg. If I visit my parents which is about a 190 mile trip each way I average about 29-30mpg. I've had my hybrid for almost 50k miles now and my engine is at 86k miles

Take out the cam bucket and set a metal flat edge across it and take a feeler gauge preferably a offset Feeler gauge go in between the cam bucket and flat edge. That will tell you how much it is worn.
