Yeah, that's what I always understood, too. So, again, the claims made on the subject site seem pretty dodgy.jpdeuce said:Because they typically aren't mutually achieveable
I wouldn't recommend a company no one's heard of or used before. Get something tested and proven.
& I wouldn't be surprised if those chips DID give you better fuel economy; if you drove like you did today; with the same acceleration curve and what not. The difference is; you likely won't. 50% throttle now would be like 35% throttle after being chipped, and who's really going to back down and drive at 35% throttle after getting chipped?
I'm sure someone could customize the code for a fuel efficient diesel though. But how low (tq) are you willing to go?
