There are plenty of tuners out there who do fuel injection reprogramming, chip replacements, etc. but I've never seen one for Jaguars, specifically. Not so sure I would trust a universal one like these:

Their claims of horsepower increases seem utterly delusional. Comments?

 

This should definitely result in some improvement as now your wallet will be lighter (thus a weight savings)!

I would not trust a universal kit.

Probably 30 or so horsepower can be obtained by a custom ECU tuning. But have whatever mods you want done first. They also will do it on whatever octane fuel you regularly use. Such a tuning can cost a few thousand dollars from what I've read. Basically they are fine tuning your specific motor while using a dyno if I'm understand it.

 

My car is remapped at a professional shop using a rolling road. It cost less than a 1000$ and I've gained around 30 hp.

Been trying to source the graphs for some time, with no success.
Will contact the former owner.

 

it basically comes down to supply and demand. one million hoda's out there and 100 programmers can help. We unfortunatly have only a few Jag owners out here state side so not too much interest overall. Funny thing is Honda is rather small in the water craft market and we cant get any tuning on that front either
