Im thinking about getting the Osiris tune done, since i am done with all bolt on mods.....theres just 1 problem.....OC. I usually have to put in like 1-2 qts every few weeks to keep the oil level maintained. My question is, how effective will the tune be with this problem? Will i be seeing very minimal gains? Is it safe?

I have a 5at g35

 

you'll see gains obviously but i wouldnt think its worth it. save that money for another engine.....used, built or rebuild your current one.
