I have no idea how to post some request but I hope someone reads this: I’d like to know the experiences of other users of Racechip tuning of the Sportage MHEV 150hp engine… Is it reliable, and does it safe some fuel too?
 
If its the one I looked up, its very expensive at about $900. My guess is if it works, it changes the ECU settings of the turbo boost pressure. This would increase horsepower, but would void your 10 year warranty and would probably cause some piece of the turbo system to fail prematurely.
