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.

Let’s just say I got dyno sheets to… Let’s just say I got dyno sheets to prove these chips are garbage. I have 1/8 mile and 1/4 mile times that say they don’t make any changes to ur car. Tried out on two different types of cars save ur money. I am thinking about starting a class action law suit so people stop getting scammed. If interested let me know you can call my attorney.

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.

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!!!
