A friend of mine was kind enough to lend me his so i've been trying it out. My question is, how accurate is this device? After several attemps I managed 0-60 in 4.83 Sec and 13.5 quarter mile. Now before I get flamed for telling a tall-tale my car has every bolt on with the ecu just being reflashed. Is this device accurate or am I just wishing..??
