tuner
A person that overcomes the factory limitations of their vehcile to gain more power, lower times at races, and/or better handling. When emmissions standards were introduced, many tuners gave up, but others learned about HC, CO, NOx, CO2 and were able to improve those numbers. When electronic controls were introduced, many other tuners gave up. but others learned the way they worked, and were able to make performance gains in their cars. What stands in the way of tuners now, is quite frequently, illogical laws that ban tuning outright, despite the fact that a well tuned engine can have lower HC, CO, NOx, CO2 and fuel consumption than one in factory specification. The same goes for swaps, even though the emmissions of a S15 SR20DET are less than a 1989 KA24E, many areas have laws that declare the Silvia Conversion illegal anyway. If you think that Japanese cars are the only ones affected, think again. Many Chevy guys have fitted LS1/LS6 and LT1/LT4 engines to older cars, bringing lower emmissions and fuel consumption in the process. European imports are also affected, as a popular swap is to take a 1.8 turbocharged engine from a VW MKIV chassis, and fit it to a MKII Golf or GTI. Still, many areas have laws written by people who don't know any automotive physics.
The Urban Dictionary Mug
It looks great. I couldn't have been happier
It’s a mug I would never find in a souvenir shop. I’m a legend in my own home.
I am very please with the mug. Thank you!
ABSOLUTELY LOVED IT BUY IT RN
Was very happy with the customer service team when I had a question. They responded to my email quickly. The mug looks really cool, makes me laugh every time I use it and high quality. I’m in love with it. Thanks!
Haylee My name is haylee sullivan and the mug is describes everything about me and i would rate it at a 5 100% it is awesome

I’m right handed and would’ve liked it better if the handle was on right side with name facing forward instead of having verbiage facing front
girlfriend loved it :) - Ian's Girlfriend
the urge to buy it and write cum on it
Purchased this mug as a Christmas gift. Can’t wait to see the reaction!
This is to test if the Urban Dictionary store rating system is working and not showing fake 5 star reviews.
These are hilarious! Great gifts. Cost seems a bit high but i couldn’t resist.

It’s a great way to store my pencils.
I used this instead of condoms It didn’t work and now my nephew is my son
Ordering was very easy and the delivery to a different address then the billing address was done effortlessly with complete correct order. Was delivered before estimated date which was very exciting. Good job well done by all.
Funny stuff! I wish the mugs cost a bit less, I'd buy more. There's an almost unlimited supply of clever slang.
awesome. came just as ordered.
Nice cup a few words were darker than the rest. But ok
아주 좋은 머그잔 나는 죽은 아버지를 위해 시원한 머그잔을 얻었고 매우 자랑스러워했습니다.
I like the mug, it’s good quality, unfortunately the customization wasn’t correct. I got the “juff” mug and instead of the definition i had a quote from one of my friends as a bit, but it just came with the definition. I’ll still give it to him because the joke still works but I am a little disappointed.
