I purchased a VOLO chip for the Scion XB 2004. Have to returned it after a month of trials and lack of results, I have a 11 plate dry cell with 30 amp pwm on my Scion with KOH.

The chip actually worsen my milleage, dropping it down to 27mpg!

I am an experienced Police Harley Mechanic with 20+ years experience, and I installed the chip correctly, it just cannot flash my ECU

Just Don't buy it for scion!:mad:
