Does anyone have experience with these tuneit power pedal pro devices? What are your impressions – are they worth the price, and does it feel like the engine has more power?

 

If you have a 3.0 Ingenium diesel, try to find a company that can change the CCF files to run a factory map. That way, you are running a full factory JLR map which shouldn't void your warranty or cause any problems, because it is a factory map. For example, companies that can activate more power will affectively tune your D200 to a D300, or a D250 to a D300 or D350.
