Thanks for the info

That is the info I was looking for, I couldn't remember if you had the N54 or N55, N55 single turbos performance mods are lame right now although I heard Burger is working on dropping their tune soon

In order to have your JB4 tune run properly and efficiently . Upgrade your down pipe, intercooler and bov. Your stock turbos will do just fine.

p.s. The stock intake is better then any aftermarket intake and it's been proven on paper and dynos. Not sure why people always think aftermarket intakes are a good idea.
Do enough research and you'll find that out shortly that it's true. "cold air intake" is more like a hot air intake considering it sits in the engine bay sucking in hot air under the hood. Unlike the factory intake has air scoops going to the front of the grill something to think about.

Like MMV said keep the stock air box just drop in a K&N filter and get some RPI ram air scoops and your set intake wise.

You know of any places in the valley who can set me up?(I'd rather leave this to the professionals)

If you do plan to do the above I would recomend upgrading the charge pipe instead of installing a BOV.

i was really only looking to get the JB4 since its a lease..

Ah ok well just incase the JB gets a little boring down the road you can always put that stuff on and take it right off.
