Color everyone I just had my 2010 Jaguar XFR tuned from velocity and an upper pulley for the supercharger they claim it was going to bring me almost 600 horsepower I had it dinode at another shop turns out it's 490 to the rear wheels and 590 to the crank to this sound right to anyone if you think this is good numbers please let me know your opinions please it would really help thank you
Stock is stated at 510 HP at the crank. Looks like you gained 80 HP at the crank. Only 490 at the wheels seems low, but someone with more knowledge on tuning and dyno numbers will jump in soon.

I think they claimed almost 600hp. You had it done, dynoed it & it made almost 600 hp. What are you asking ?
Dyno results are meaningless without seeing both before and after figures. Comparing the before and after shows you the real gain. And every dyno reads different (mustang dyno vs dynojet), so just seeing 490whp doesn't confirm nor deny the 600 hp claims.
We just did an ECU tune for a customer on 2010 XFR. On street tires with not the best traction he went 11.9
With with an additional 50 Shot nitrous we got 11.4 so farProbably the fastest result for any XFR out there.
