"I have had two separate 'Ron boxes' and…"

I have had two separate 'Ron boxes' and both have shown a great improvement in drivability and power. Much cheaper than all the rest and better than most. We'll done Ron.

"A better diesel Range Rover P38, thanks Ron"

I've bought a Ron's "SYNERGY 4B (VP) FOR THE RANGE ROVER 2 P38 2.5L 6CYL" some months ago.
I've installed (setting 2 with fueling half way) on my 220.000 Kms 1999 Range Rover P38 2.5 DSE with automatic transmission and now, after having run some thousands kilometers I can write my opinion :
Simply I have a new car, it's unbeliavable and fantastic !
I can run with the cruise control at 50 mph without hearing the gearbox switching between the 3th an 4th speed continuosly at each small hill, now the engine have enough power to keep the 4th speed quite everywhere.
I can overtake a car on the motorway with the 4th speed.
The p38 is a heavy car and don't believe that with some power more you can obtain a nervous car, but with this Ron's tuning box driving my Range Rover is a real pleasure.
The P38 calculated fuel consumtion is really lower, the real fuel consumtion calculated is 1 liter less for 100/kms, I'm now at 10,2 l/100 Kms and without the Ron's box I was at 11,2 l/100 kms in the same conditions.
Thank's Ron for your help to improve my Range Rover qualities.
