Does not work as Advertise at all! I got the chip stage 2 for my RAV4 and I let it in the car for 3 weeks (instead of the 2 suggested) and not only didn't improve the miles or give me more power but on the contrary I felt the SUV to be more lethargic then usual, and the miles when down by 3! I paid for shipping back ($11.15) and they also charge me 15% restocking fee?!?@ Their website states 100% money back warranty. I will not recommend this company to my worst enemy!! Update: They reply with lies as you can see below. I have contact them and send it back in the original box with no a scratch in the time allow. I have all corresponding messages and pictures.

Great Product, Great Service I bought a stage 2 chip, and though it was a significant power increase, it caused some surprise redline downshifts with my transmission when letting off the gas after full throttle. Contacted customer service who were very helpful. Replaced it with their JDM stage 3 chip and it is performing flawlessly. My Crown Victoria is now positively FEISTY!!!

Beware of Electrical Issues I am no expert but I did notice performance gain on my 08 Chevy HHR SS. The problem is the chip caused some electrical issues. When I first installed it some fuses were blown immediately. I replaced those thinking its just a one time issue. Used the chip for a few more weeks and then one day the ABS light came on. Took it to my mechanic and it turns out that the ABS module/system was gone. Now I cannot say its due to the JDM chip but I had never had electrical issues with the car before installing the JDM chip. So yes it does increase performance but beware of electrical issues at least if you own the HHR SS. No plans to use it anymore. Will go back to my Pedal Commander which has always worked well for me. Yes I know they are not the same but I am not trying to race anyone.

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.

GREAT customer service I recently bought a GTE Stage 1 OBD2 TUNER for my 19 Abarth spider 124 and love it. Got it within days ! I then ordered a code reader, but only goymt the order confirmation for order 162080. I called after a couple of days and got right thru and it was resolved ! I will be doing more business with the for sure.... VERY RESPONSIVE
