Placed order for a cortex programmer for my 2004 duramax. Best price with fast free shipping. I couldn't ask for a better company to do business with.

Shopping was quick and easy with the link to Amazon to pay.

Was fast and easy to look for parts and order.

It was very easy to order my husbands part.

Great experience! Shipping was fast and the price was amazing. I'd actually wondered if it was too good to be true, but my ramps showed up today (exactly a week from when I placed my order) and they look great.

It took exactly a week for the part to be shipped because the part came directly from the supplier. But the price was the lowest around.

the order was quick and inexpensive. I would have bought a carb if I could have found an Edlebrock I am not a holley fan sorry.

Good website!

Quick and easy. Takes PayPal

So far it has been a good experience

Very quick and easy. And the price is the lowest I've found. Juse wish it would have stated somewhere that you still have to have the keys reprogrammed.

Great service and communication. Once it was shipped, I was able to track my item. Best price I could find on the internet!! Would definitely do business with anytime.

Very easy to find my way around the site and great deals!

This vendor has good prices, would give 5 stars if free shipping.
