hello me again
thank you for giving me brenspeed.com great service, I gave him a call and I am between x-cal and performance tuning but I am trying to figure it out
it seems that the tunning software is just a matter of time to master it, but I just have one question
x-cal, who has it and what kind of gains I can get
K&N, Ypipe, resonator changd to magnaflow
thank you
