I was planning on getting my car tuned in the next few weeks but I was wondering if it would be beneficial to wait until Aug when I get my new wheels and coilovers or does it not make a difference.

I haven't decided if I'm going with 19's or 20's but am definitely going for a more aggressive style but still want to keep performance. So I don't know if that could throw off my tuning if I do it before I get the wheels.

BTW I was thinking black Axis Angles or black with a polished lip Volk GT30's. Both generally come in 20's but I have seen some 19" GT30's while searching.

 

I say go for it sooner rather than later if wheels/coilovers are your only mods coming up. That shouldn't effect a tune. 20" wheels are heavy but look sweet... if you care about unsprung mass.

 

That's why I still haven't made up my mind on which size I want to go with. Still not even sure on which wheels I want. I have 6 months to find a good set but the angles and gt30's are the two front runners at this point.

 

How much is an Osiris tune? Also, where can I get it at, certain tune shops or how does it work?

 

Well it depends on where you live and how much the tuner is going to charge you. To buy the Osiris just itself and just plug and play I think it's around $500. You will see the most benefit out of it if you go to a tuner and have them set everything up specifically for your car.

Since I'm located in the LA/OC area I'm going to Church because I've heard great things about him through G35driver and it's only $50 extra to get an hour tuning session on a dyno, IMO well worth the extra $50 to have a professional tune it and get the most and best gains possible.

Go to UpRevs website and search for a tuner shop near you.
