Can't get ahold of them to return a… Can't get ahold of them to return a product Update: Got a call from their customer service department. I don't know why they didn't receive my email, but they really stepped up to the plate to resolve my unhappiness. They were really great to handle this situation after contacting me. PSA: The stage one tuning chip is the bomb!

Great product and great company. Great product and great company to deal with. There are quite a few performance chips out there so a little research lead me PCT. it does as advertised. I ordered the Stage 1 for my 2016 CX-5 and after setting it up, the Mazda is purring like a kitten. It idles better, definitely is showing a performance enhancement and I can garner from these immediate results, the MPG is going to improve as well. Very happy with this addition to my SUV.

2006 Dodge Ram 4.7 I wread up on the JDM stage 3 a few months ago, an, actually put headers on my truck like days before the device arrived. I'm running 22x12 on 33's so acceleration/ power has always been a must! The thing bleeps every 10 seconds like a alarm system, but, my Dodge came alive within the hour of plugging it in. I love it, and won't drive far without it ever again.

It actually does work.... OK... finally got the miles on the chip that they required. It actually does work. Not sure how much horse power it added to the car but I can tell a difference in acceleration and shift points. I did hear back from the company about the questions I ask.. about a week later. I guess later is better than never... I am gonna get one for my 6.4 Ram next.....
