DiabloSport® 18GBC - Gateway Bypass Cable

While the tuner took an hour or so to get connected to the internet to update, the process of applying the tune to my car was painless. I'm running the 87-tune, and I can DEFINITELY see an improvement in performance. Throttle response is nearly instant, and has noticeably more low-end power from the tune, even on the lowest octane tune. I highly recommend for one of your first mods.

It's easy to program the ECU according to the screen indicates. I use 91 octane Diablo tune, I feel it gains more house power and torque after it's done, the accelerator is getting more sensitive. Best chip ever.

I have a 2006 Dodge Charger SE High Output 3.5L V6 with 316,000+ miles. The car already ran well and never lost its pep. I saw some reviews about this tuner and it is compatible with my older vehicle. The setup was quick and I was able to backup my current PCM configuration (Factory) before applying a Tune. I used the 91 Octane setting and made a couple of changes; remove speed limiter and increased the shift stiffness. I could feel the difference right away. I picked up a friend and they noticed the power at the throttle too.

Does not come with pcm. I noticed now that it did say it in description. But still, waste of money if you can't even use it.

I purchased this for my 2005 Jeep Grand Cherokee and the website said it would fit. When I got it I was getting error messages and was told I would be contacted in a few days. It was about a week before I heard anything and tried some trouble shooting but kept getting the error. I contacted the manufacture and after about 2 hours on the phone with them and them talking to some technicians we were told that the part doesn't work on my model of jeep. The tech said that if it was any other year/model then there would not be an issue. This only affects the '05 jeep grand cherokee 4.7. This model is black listed for some reason. I really wanted this to work. I don't blame CARiD for selling a part that doesn't fit because the manufacture listed it as working on their website too. CARiD was great with working with me on getting a refund. Just a warning for any other jeeps wanting to get this.

Came on time, well-packed, and as advertised. All the preloaded tunes work great. Very noticeable difference in performance power. Easy to use, just plug and play. You can also find many helpful tutorials on Youtube. Good product for the price.

This tuner is sure to improve your factory settings and make your vehicle more custom-looking. Love all of its preloaded tunes. The tuner is of high quality and easy-to-use, but as for me, its price could be lower.

This programmer has literally woken up my Ford F150. It slightly helps with the gas mileage but power gains are significant. User-friendly and reliable device. The only issue I had with my purchase is that the delivery took way too long time.

Does everything I needed it to do with no complaints. Easy to use everything is self-explanatory.

Works great on my RAM 1500. I was looking to increase throttle response, and this tuner is the perfect way to do this. Plus, it adds horsepower. My truck performs so much better than it did before I installed this one. The fuel economy is also slightly increased. The tuner is expensive but worth buying.
