Audi GEN 3B A3 8V, A4 B9, A5 B9 Performance Tuner

The JB4 is a plug and play Audi tuner that plugs into easy access sensors in the engine bay The JB4 is a plug and play Audi tuner that plugs into easy access sensors in the engine bay and works with your factory ECU tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag. It features a 64mhz processor allowing sensors to be sampled 800 times per second using dedicated 10 bit digital to analog converters, ensuring smooth and powerful performance. Minimum power gains of 30whp and 45ft lb on 91AKI/95Ron

Now includes the JB4PRO adapter and free app built in!

Unlike other tuning systems, the JB4 includes a fully programmable CANbus system, at-home upgradable firmware, and data logging capability. CANbus allows the JB4 to access engine data to take into account pedal input, throttle position, gear, engine speed, air/fuel ratio, fuel trims, ignition advance, knock, and many other factors and incorporate those into the performance mapping. It can also read/delete fault codes, incorporate unique safety features such as keeping boost pressure low until oil and water is up to temperature to provide proper engine and turbo lucubration and drop to a low boost map if the engine starts to overheat, run lean, excessively knock, or over boost.

The default JB4 map1 runs 3psi over stock peak and tuned maps, including stock and valet mode, can be selected on the fly using the optional wireless JB4PRO bluetooth adapter. 

Installation is very discrete, and it quickly removes without a trace when needed. Fuel economy during normal driving is unchanged. Compatible with all driving modes. 5-year warranty.

Very disappointed
Color: Enno
The toy was split into pieces in the first 5 minutes of the dog playing with it. Apparently not as durable as advertised.

Dog toys need to be sturdy - maybe you should sew them with a 5-thread machine like a serger?
Color: Elroy
My dog's full size teddy is disintegrating, so I ordered this one. It's very cute, but the seams are really weak. I've already repaired 3 seams in just a few weeks.

Great toy!
Color: Elly
Great toy! Dog loves it and it is durable. We’ve bought other toys that he tore apart within a week, not this one! He takes it everywhere we go!

This plush, well sewn dog toy has become my dog’s best friend
Color: Enno
This adorable plush dog toy has become my dog’s best friend( besides her big lab brother!) and she just loves playing with it. It is made and sewn well and holds up to her keeping it in her mouth and then tossing it around her. I searched on Amazon for a soft, medium sized stuffed animal for her that she could nuzzle and hold in her mouth that did not have a squeaker as the sound scared her. This Trixie Be Eco Enno plush dog toy has been the perfect choice. It is carefully sewn and even has no dangerous buttons that she could chew on and pull off and swallow. Rather, the eyes, nose and mouth have all been carefully and adorably sewn into the dog’s face. It has stood up to wear and has not torn or come apart. It has been well worth the money I spent and I’m glad Amazon carried this nice toy for her.
