Great

Excellent, GREAT PRICES!

I ordered the Edge Evolution CS for my 2008 F150 and it has brought my truck to life. Setup was simple and I could immediately feel the difference in the acceleration and transmission shifting. I would definitely recommend this product.<br>Autoplicity had the best price on the tuner that I could find for brand new. However, they did charge for shipping and it was slower than other sites I looked at. Overall, I still got the tuner cheaper that any other competitor.

Very fast shipping and order processing!! Extremely competitive pricing; after wading through the internet and finding 'good' pricing (from sketchy vendors) these guys are tops!

Thanks

received a follow up phone call within a hour letting me know that my order #5153 would be coming from a certian warehouse and about what time it will arrive...Great service!!!highly recommend
