" Jeep Cherokee 3,7 (2007).I have always applied OBD-tunig in my cars. Thus, I could unleash full potential of the engine, which may often be hidden by the manufacturer. It wasn’t easy to find good firmware for Jeep Cherokee, that’s why I’ve made a decision to try and purchase the RSchip. And you know what? After installation, I managed to feel power gain, though I was said the biggest power gain potential would be reached after 200 km. Now it drives much better, and the results are quite satisfying. It’s also wonderful to save fuel consumption. By now, my driving along with fuel savings is just incompatible! "

" I purchased the RSchip 2 months ago. It was really hard for me to install it. However, I finally managed to wire my power box, and it took me 20 minutes. I was able to feel the differenceafter upshifting from the 2nd to the 4th. Primus began gaining speed faster than before. No jerking and lagging are noticed. That's why my engine’s nice thing to work with. "

" A friend of mine told about the RSchip. He actually made up my mind and I ordered it. My parcel was delivered very soon. For me, installation was fast and easy enough. There is a good step-by-step manual, which is well-written. It provides comprehensive guidance for everyone. After the installation, my Opel got even more responsive, especially at lower RMPs. Besides, there were no throttle delays. Km per liter thing doesn’t matter for me. This purchase lives up to the expectations. Many thanks to RSchip team! "

" I’ve been looking for an appropriate power box for quite long time, because it’s not easy to find anything worthy for Toyota Land Cruiser, like I have, with petrol engine. When I installed it, I was informed that it might take around 200km to feel the full power of the chip. Then, I really felt significant changes! It drove smoother, and the car showed more responsive performance, mostly in low and medium RMPs. "
