I ordered a stage 3 O2 chip. Before the order was sent I received an email saying they had another item that 'most' people bought with the original item and because the box was opened it would be discounted 50%. In short the O2 chip was great, but the so-called blower was a joke. Not only did it require a part that had to be fabricated to make the hose connections, but it made my 4Runner run so badly that after paying the $180 part cost, $130 connector fabrication amount and $60 installation fee I had to have it removed so my car would start shifting gears again and not shutting down. I only had 38,000 miles on my car so I could not chance that this stupid 'blower' would cause major damage to the transmission or other components. I contacted them explaining what I had experienced and of course no response of any kind.
When I ordered this first part they refused to send it to my shipping address because 'virtually always it was a scam' so it had to be shipped to my billing address which caused me to pay sales tax, double shipping since it had to be forwarded to my shipping address and a two week delay in forwarding the items to me. What they failed to say is that they are the scammers and buyers should beware of them.
