As everyone knows the the engine on the TDV6 is from jaguar... and it originally develops 275 Hp, but it's has been lowered down to 245 in the RRS.

Obviously it's a marketing consideration, the TDV8 would be killed by its cheaper same powerful TDV6 brother...

Question is : how can we recover those 30 Hp ? then (and it's the target) remap to reach those kind of numbers :

for example: http://www.ziptuning.nl/en/customchip/Jagu...tml#header

from 275hp & 600nm the 3.0 V6 in the jaguar XF raise to 325hp & 673nm.

Thanks in advance!
