Bought an ebay Xtreme otr for my maf tuned vz ss ute 2 weeks ago, its the best performance mod i,ve done yet. I still have my maf between otr & throttle body, installed myself, little bit of work, nothing major.the throttle response is better & better fuel economy. Have done all other bolt on mods. The guy that sells them is very helpful.
