This is not a chip of any kind, it is a resistor in a box. I purchased two of these "chips" before doing my research, boy am I sorry. I had to email the Redline guy for help on installation, he was quick to respond to that email. After I installed the "chip" using his instructions my check engine light activated. I took my van to a mechanic to find out that the chip triggered a low voltage to MAS on my intake as well as false readings to my ECM. Now the fellow won't return any emails.
So here I am $95 in the hole and nothing to show but a headache caused by this scam artist that says "5000 people can't be wrong". Well if you read the positive feedbacks you must realise that at least 1000 of the people left them before even installing the box, another 1000 left them within 12 hours of installation, and the rest were just trying to get their money back by leaving a "creative feedback" as stated by the seller on the peice of paper shipped with the "chip".
For the feedbacks that actually state that they "feel the difference", that is due to 2 reasons:
1. they are pressing on the gas harder in hopeing that the chip really works
2. the "chip" tricks the ECM/ECU into thinking it's cold thus dumping more gas into the motor. This will mess up your engine, throttle body, and injectors over time.
I hope that eBay will ban this guy for fraud, simply because a resistor is not a performance chip, it is a resistor.
