[QUOTE="b00stin, post: 11765494, member: 87701"] So i went to get the vehicle tuned today... the car has been kinda falling on its face when shifting to second gear light throttle driving. i thought because it wasn't tuned yet this is normal.. so i take the car to the tuner today and i get a phone call saying there is an issue with the vehicle that it is falling on its face and won't accelerate or basically do anything and it is puffing black smoke. they said that it could be bad injectors.. so they swap them out with known good ones, it doesnt change. now they say that it could be a bad mass air flow sensor. the sensor was brand new out of the box... i checked for any leaks in intercooler piping or anything abnormal and i found nothing. it sounds like the vehicle just isnt tuned to me and is running rich.. i then called pro-m and they had me back probe the connector for the mass air flow and check the voltage output at idle and while reving. .5 volts and idle and up to 2.1 volts while reving in neutral. pro-m said this is correct and the mass air flow is fine...kind of stumped at this point. the tuner said to swap back in my stock mass air flow and injectors to see if the problem goes away.. but that just doesn't seem right and basically a waste of time if we already verified injectors and mass air flow were fine...
