The dyno is simply a measuring tool as Cambo said it's not gospel . The main factor to look at is the xk made a proven 10% increase in hp and 8% increase in torque
The vehicle is absolute pleasure to drive now with decent torque down low so I'm finding no need to continuous drive it in the higher rpm band to get the same effect

Results last night temps didn't drop below 34c so very hot
Xk jaguar as tested by motor trend - 14.3@98.3 & 14.6@97.4mph
Xk jaguar - 100 cell cats + custom dyno tune constant 14.0 @100mph and a best of 13.9 @101.5mph
Considering a n/a xk 5.0 runs 13.5@105mph we're a lot closer to that mark now with the simple upgrades
