Does what it claims Does what it claims. Put Stage 1 on my 2007 Accord V6. Immediately noticed car running smoother, more responsive gas pedal...seems to react higher on the pedal too. After 48 hours, it's still improving. Transmission shifting more softly, can feel a smoother power band. Found two reviews by professionals online. Both came up with similar results. Worth the money.

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.

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.

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!
