So I traded in my 07 FJ cruiser for this, my mom wanted practical I wanted speed so we compromised she liked the AWD. Anyway got some questions, what kind of quarter mile times am I gonna get stock, I've heard around low 14s to high 13s. Can. Anybody recommend a good tuning chip that's not going to break my budget $400 or less. Also looking at getting an exhaust if anybody has one they like that would help too, like loud but not something that screams ricer. I would like to supercharge eventually and I know stillen is the recommended company but are any others better? If anyone saw my other thread on the aux cord issue what do you use to play music from your phone. Last thing I noticed that I wasn't sure if all g37 are like this or just the x, but there was hella throttle lag. Once it gets going it goes but my FJ had a little quicker response (it was stock) not much to compare to considering it's 2 completely different cars.

 

You have a lot to learn. Start by poking around the Tech forums. And saving your money because nothing that improves performance can be had for $400. Except maybe K&N panel filters, and they are a marginal gain. You can buy dress up stuff for that much, though.
