The gas mileage is definitely improved. There's no question about that. By how much? I can't really say, but it's steadily improved from 19.9 to 21, and this is including an auto-cross and some high performance "testing" of this chip.
The throttle I cannot compare to the sport mode because I don't have that
Eslai: Are you kidding? I've spent months and months trying to find a single product that guaranteed themselves so I would not have to waste $$.
I don't know if you remember when I joined but that was the first thing I asked about; Mods.
I am a very skeptical person but I also realized that spending months & months debating on whether or not I want to spend a few hundred dollars doesn't make any sense either, so I decided to take the bait and see what's up.
Sometimes that's the only way to really know...
Anyways, I think that instead of a PSE, I am going to buy a 1st gen. Miata for track driving and auto-crossing. My car keeps getting all dinged up.
