In my personal experience, you're talking out of your arse.996TURBO said:Those power boxes are bull****, they all work on same principles. There's few electronics in there. Basically there's 10 GBP max of components.
All the boxes are the same for all vehicles, some even say they're universal.
Those gives more fuel pressure, more fumes, more power.
Of course you'll get more power but not with the safest method for your engine and transmission because it's not bespoke for your vehicle.
A box is cheaper than a rechip but a decent rechipping will give you power but with safety and reliability.
-More Power. Did i say that the box won't give more power? No of course they will and that'll help you when towing or passing.Cornishman said:In my personal experience, you're talking out of your Golly Gee Whizz.
I had the PSI powerchip fitted to my Discovery 2 TD5 and Shogun 3.2 DiD, it gave much more power on both vehicles, so much so, that when towing a bobcat with the Disco, I could climb local hills in a higher gear and still accelerate.
This came with lower emissions, proved with an MOT station exhaust analyser, as I was concerned with emissions. Unbelievably, it did give greater fuel economy on a long run.
Sounds too good to be true, I know. But the facts are, that's what it gave.
They are not universal, you buy a unit to suit your vehicle. Okay, their not tailored to suit the individual engine mapping, but in my case, they did nothing but good :thumb:
