Received my Ultimate9 evcX530 yesterday. I've had a chance to do a bunch of driving around and playing with the settings and I REALLY LOVE this thing. WOW!!! What a difference in throttle response and how the truck drives now. I've had Pedal Commanders in the past and this puts the PC to shame along with the Sprint Booster. 5-minute install and you can either mount and use the microcontroller (as seen in my pics...very small), or you can also use it via Bluetooth with an app on your phone with or without the microcontroller installed for a stealth appearance. It also has a LOCK feature that locks out the accelerator pedal in case someone tries to steal your truck...the pedal will not function. If you are interested in bringing your ZR2 to life and eliminate throttle lag that these trucks have, this is a must buy and I highly recommend it!
