Re: first to 500 hp
I, too, was one of the fortunate ones to meet Jeff when he opened up his shop for all XF owners who cared to take a drive down to Southern Maryland. He and everyone involved with his operation were the greatest. He offered all labor for free and all you had to do is bring whatever you wanted changed, installed, etc. His guys installed Rotex pads, worked on intakes, corrected electrical problems, diagnosed suspension issues, whatever anyone wanted. And he wants to periodically have meets like this again!
The mods he did on his SRT were beyond professional - they were incredible. I would challenge anyone to do a better job. His NOS install was not some kit just slapped on - everything is done right including a minature touchscreen computer to control the whole set-up. I guarantee that the purpose of his post is simply to add to the enjoyment of all here on the forum and to raise the bar those who wish to push our XF's to the limits. Those who do nothing more than pound on keyboards should try to do something better. I, for one, will just have to sit back and admire the work of someone who will forget more about cars than I will ever know.
I think we Maryland area XF owners are lucky to have someone like Jeff around with his knowledge and generosity.
