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!

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.

It cost me a $200.00 repair bill It cost me a $200.00 repair bill for my 2007 Cadillac Escalade. The performance chip interfered with my EBS and Stabilitrak system. It affected my ride, and my braking, and after taking it off and throwing it away I feel like I'm riding in a completely different car. Whatever difference it was to supposed have failed to materialize after 1,500 miles.

Chips don't work and could cause electrical issues I personally used this chip for 6 months now and have driven close to 5000 miles with it. They do not do anything at all to your vehicle and could cause electrical issues like what happened to my 2010 Ford F-150. I did some more research and it looks like they have two reviews blogs that they own, one to help give positive reviews to their chips and one to give bad reviews to competing chips. I am not saying that you shouldn't buy from them, I am just saying that you should do a little more research before you spend your hard earned money on something that could harm you car. Tried to contact them 2 weeks in and they kept giving me the run around then they said they couldn't help me or give me a refund, its a shame, I really wanted to like this company and their chips.

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.
