The DINANTRONICS X is the newest installment of the highly successful Dinan foray into inline tuning modules. Like its predecessors it is a highly engineered piece of computer hardware and software that enhances engine performance to levels the stock programming is not allowed to venture. It does this without affecting long term reliability or the functionality of on-board diagnostic systems when run under recommended operating variables. Unlike its predecessor however, the DINANTRONICS X is Bluetooth smart and offers convenient access to the adjustment of power levels directly from the palm of your hand.
A further advancement beyond its entry level little brother, the DINANTRONICS SPORT, X connects to additional inputs and/or has a more refined tuning strategy that yields more power as a result. For those that do not wish to (or can't) alter their stock ECU with a more robust engine flash the DINANTRONICS X is a perfect alternative to satiate the craving for "more". Whichever level of engine tuning is ultimately chosen you can be sure to be pleased by the result. The Dinan Difference is possible by employing a full staff of talented engineers that are well rounded in many facets of automotive engineering and backed by a wealth of hands-on knowledge. Stemming from diverse backgrounds not only on racing teams but on standard factory production line vehicles, we have seen it all. Manipulating these signals/maps with an adept hand, all the while keeping an engine running at its best and with the most reliable power, is what Dinan is all about.

Absolutely adorable
Bought for my twins, in two different colors, absolutely frickin adorable. A little too big for them, but they're small for their age. Wish it came with a shirt too, but we just bought them separately. Durable and well made. Definitely worth it.

Runs small but great quality for the price
Size: 10 Years, Color: Black
I sized up hoping to get something a little bigger to grow into, however this suite runs small. If I had ordered the real size it would be too small. I ordered a 7 for my 6 year old and a 10 for my 8 year old. The size 10 was missing the suspenders and came with a real tie not a bow tie unlike what is in the description.
