How can it do less rpm at a set speed because of a tuning box?? Anyway that aside I've been in to work to investigate a weird transmission related noise, found a knackered prop uj, replaced that. Noise is still there but less noticeable now, suspect inner cv joints.
The tuning box gives the option of increased torque, therefore more power. If you have more power the rpm drops due to the engine not having to work as hard.
There are some interesting explanations on the net about the technicalities of how this works. A lot better than I can!

I understand all that, I'm just struggling to understand how it can alter your gear ratios! Lol
I think what he's getting at.... is adding more fuel, can't change what engine speed is required for a set speed.
EG: Mine will do roughly 70mph at 3000rpm. I can add the largest turbo in the world, nitrous, etc... it will still need 3000rpm to do 70mph.
To change this, you'd need to change the gearing. Or, it's cocked up your speedo/tacho sensor, making the clocks read incorrectly :lol:
To get that extra torque, it pumps in 20% more fuel, so that you can put it in a higher gear and achieve a 20% reduction in revs!
In pumping extra fuel in, less accelerator pressure is required. Or you can turn it off and put your foot down a bit more.
Of course a guy in a garage with an Apple Mac can get more power AND fuel economy AND reliability out of the engines than the combined might of Land Rover, BMW, Bosch & all the motor industry analysis. Maybe he just knows how to kick more s**t into the atmosphere.
Grumpy by name! Placebo.
