tuned xfr 2010? or okay guys has anyone put that chip on their car that's supposed to make more horsepower I saw one on eBay for like $60 and all they say is you plug it in your computer module under the dash and it's supposed to do a lot for your car if anyone can give me some advice that would be great I don't want to waste my money

 

Don't do it.
Those cheap OBD2 port plug in "tuning" chips are pure snake oil, at most they alter the throttle response, and they do not and cannot increase power or torque.
However you can tune a 2010 XFR for sure, several tuning companies out there that do it including Velocity AP and Viezu.
Or you can fit a proper tuning box such as that made by RaceChip. Either way will cost between $1,000 and $2,000 US.
Plenty of threads and posts around here and on the XK and XJ sub-forums about tuning an older (eg 2010) AJ133SC, just remember that the older engine uses a Denso ECU while the later ones (2012 on I think) use a Bosch ECU, and the tunes and chips are not interchangeable.

 

When you have a 25K car, that costs a fortune in upkeep and even more to get serviced, its not a good idea to go cheap on an upgrade... IMHO

Do it right or don;t do it, you have a car with 510 hp, no reason to think and extra 50 HP is even worth th echance of messing something up

@OzXFR is right, it may alter driving characteristics ( I say might sicne I very much doubt it) but not really "deliver the goods" as promised

 

What they said! The cheapest route would be to buy what's called a "canned tune" or one that has been generally developed by a tuner for your car, I've had good luck with this type of tune both past an present, but it will still cost you about a $1000. The closer your car is too the original tune car, the better your results will be.
