Osiris Tuned: Dyno Sheets FTW!
DO the basics, plenum spacer, intake of some sort at least z tube, etc etc. THEN get the Osiris and tune. Trust me you will waste massive amounts of money and kick yourself in the **** if you do it with just two mods. You can get The spacer and intake starting at less than 250$, if you wait and need a retune you will spend at LEAST that just for a new tune.
Hope that helped
MULTIPLE factors come into play here. What type of dyno is used, temperature,elevation,what type of gas, if the tune is extreme or safe for daily driving,and the list goes on and on.
You must remember, all tuners have different ways they do things, 2 identical cars with the same mods but tuned by two different people,or the same exact person but on two different dynos or in different climates, can produce completely different numbers.
Also a good hint, the "estimated,or stated' hp gains are almost NEVER dead on. A lot of time they are not WHEEL HORSE POWER,which people dont realize,or they are listed as the max but with complimenting other mods that arent talked about. However MD is one of the absolute most honest,best companies making parts for our car. Take a look at the dynos on their site,they have extensive topics to answer most of your questions. If you must,call them and ask for Tony, he is an absolute pleasure,and is very very well connected with the g35 community.
good luck! the mod bug bites hard

Hey man just to help you out,think about this for a second.You should really take a step back and wait. You are going to spend 500-1000$ on the Osiris software and tune. To only have two mods would be a waste, then every time you add anything else you will need to go pay hundreds more for re-tunes to get the advantages of each new mod.

To make the etunes work you'd have to install an aftermarket wideband and repin the OBD2 connector yourself
What bolt ons do you have? Also uprevs site is user friendly to get the proper items for your vehicle.
Just have the z tube with k&n filter and the 5/16spacer but am ordering art pipes when i get osiris since i got rid of my toy thought i buy a few things. Not surr what i wanna do for rest of exhaust yet.
That dyno is from about 1.5 years ago. I added berks HFCs and Tanabe Medalion exhaust and lost 3hp and 1lbft torque. Anybody know what going on. The shop recommended getting a y-pipe but since I'm AWD there aren't many options.
Just had my car tuned at Church's a few days ago. Im happy with the difference the tune made. The car defiantly runs better but I want more. Should have gone FI right away.
Mods:

5/16 plenum spacer

Osiris tuned 391 rwhp 320 tq on a pretty safe tune
That's crazy, I had completely different mods on my G but got the same numbers after tune when I had the stock engine. I've since replaced the whole engine and just got retuned at 6psi. I still want to do the fuel return mod and install a MAF GT before I push beyond 400whp.
