No I upgraded to a Big 16G recently but I just had the motor blow up and it sat for 10 months. I actually just got it running a few months back, but it still runs a little meh. Also I didn't get my new front bumper painted yet so it still looks beat haha. The paint is stock its called Cayenne Red Pearl.
If you have a dremel or a air compressor all you need is a grinding stone or a grinding bit. The intake manifold is actually about 54mm stock and since the throttle body is 55mm you only need to go about 1mm bigger but I ported my Intake manifold all the way out to 57mm just incase the throttle bodu didn't line up perfectly. You can use a micrometer and hold it up to a mm ruller or you can just use a mm ruler to measure the diameter of the hole
I promise you can do it yourself. All you need is die grinder or a dremel and sandpaper. Taking your intake manifold is very easy. All you néed to do is Jack up your car go underneath it and you'll 5 bolts holding the upper half of the intake manifold on. You'll need like four 6 inch extensions and you'll be able to reach all 5 of the bolts. After that all you need to do is unconnect all the sensors and undo the two boots holding on your throttle body. The only other thing you really have to do is unattached the throttle cable. Trust me it is much easier than you think I'm 17 and I did it in 30 minutes. Hope this helps.
I ported out the intake manifold my self with a die grinder and then smoohted it out with sandpaper and then polished it with scotchbrite and wax. I bought the throttlebody on ebay just type in 420a 55mm throttle body. I ported the intake manifold to 57mm just incase the throttle body didn't align perfectley.
