Re: Predator Tuner, Vararam INtake and Velocity Stack (arbrmdangus)
I have a blackwing and velocity stack. I used the Predator and a custom tune from James at RWTD to help with my A/F ratios. You have to look at the O2 mV values. I try to keep mine between 900 and 930 if possible. I also have LT headers and this custom tune helped with this. Also, Check you LTFT's, they should be neg. in the range of -1 to -4 any more than this and you are too rich. Dont flame me for this knowledge, this is what I have deduced over the last 5 months of searching several sites on how to use LTFT, STFT, and O2 mV reading on tuning. Your results my vary. If you have acess to a dyno with wideband O2 capability, it will be easier to tune. Good luck! :seeya
