Well I went with Stuart with AP. He just has had a lot of good success with the 5.0L SC engine.
I am in the US and AP is in Canada (after moving there from the UK) so you should not have any problem with getting the tune in your country.
It comes on a USB drive so no need to remove the ECM and send it anywhere so your car is not down at all.

I have never seen any results from the tuner you mention and I would listen to Cambo about tuning/modifications.

Well if cambo can recomend where or send link wheren to get the best tune will be glad.]]]

BUT i did make progress today, I changed the complete belt tensioner, JAGUAR seems to have a upgarde, which puts the pulleys in diferent locations, so it ends up being far from the water pipes, like 2 INCH clearance, instead of 1/5 inch lol.

it came with plastic pulleys, and groved including the tensioner one, I ALSO DIT alligmnet of pulleys , with some light sheem washers from behind, so the belt runs straignt, NOW belt runing without any movment or slip, or squuel.

I NOW HAVE NO LOSS OF BOOST< AS SOON as I HIT THE THROTLE DOWN IT INSTANTLY I HAVE INSTANT 8 PSI, from there it JUST steadily goes up to around 11.5PSI, at over 140MPH to around 12.5PSI at 6250RPM>

SO THAT MEANS NO OVER SPEED ON THE CHARGER, AS THE BOOST JUST CLIMBS WITH RPM!!!!!! AND ALSO NO slipage of belt, BEFORE i would get to 9 PSI, at around 4000rpm, and then start loosing pressure as low as 5 PSI on 6250 RPM<
I did find lots of fine shreded dust from the belt around the pulleys, engine bay etc.

BUT no more, holding fine for now, .... even when hot, I NEED a COOLER THERMOSTAT, anyone KNOW where to get one THAT OPENS AT LOVER TEMP, THE engine BAY gets DAM HOT when the CAR PUSHED to the limit... LOL

 

pictures still not attaching???

 

One little suggestion with the engine temps - have you taken the plastic engine cover off and left it off?
It traps quite a lot of heat and there have been tests done showing the engine temp is 10 or 15 degrees lower with it off.

 

Ya, cover off since. .lol, I had it off since I installed a temp. Sensor by the inlet of the water for the intercoolers.

 

What upgrade for the tensioner? Do you have a part number or source?

Also, what kind of temperature differential are you seeing on the inlet/outlet of the intercoolers?

 

try check my other post I think on track issue, should have most info and picture on tensioner,

Jaguar has renumberd the parts , and there is a new complete tensioner unit, diferent angles and the tensioner pulley is plastic , instead , of metal, the older metal , can be ordered only the part with mettal wheel,

the one with plastic is one big bracket, 3x pulleys including one for the aletrnator belt.
