I just bought my car the other day and they pumped a full tank into it for me. I've been driving it and right now it seems I've put about 200 miles on it and the fuel gauge reads a little over the 1/4 mark. I don't think I'll even reach 300. Of course I've been testing the car out so that'll probably affect it, so hopefully my next round of gas I can test it more.
My car seems to hesitate a lot. I'm not 100% certain if it has been reflashed. I called Mazda today and the service guy couldn't tell me jack. He didn't even know about the flash. Under the hood there is a label that states "Mazda Authorized Modification", but I'm not sure if it is for the flash or something else.
Should I waste my money on the flash, or should I just invest it in getting the DSM AFC? Will the DSM AFC fix my hesitation problem and also give me better gas mileage? Right now all that is in the car that I know of is an Injen CAI, Autometer boost gauge and A/F ratio gauge.
