So my 6mt g35 now has CAI, stillen headers with straight 2.5 inch piping (x pipe) back into megan mufflers. Any idea what numbers I should be looking at before and after tune? Anyone done a similar setup on a sedan hr? Any info helps and thanks!

 

Those are pretty standard mods, and its hard to say what a tune would get you; probably not more than 10hp.

I do NOT want you think twice about getting a tune strictly because of power tho. While it may not result in a 30hp bump, the difference in driveability, smoothness, throttle response and overall enjoyment of driving the car are bar-none the top reasons to get the Osiris tune. It has been the only mod that I have not grown tired of or "used to". Its easily the best mod money can buy whether dead stock or fully modded.

 

Yeah its bogging a bit and getting kind of annoying. Thanks for the info. and hopefully all is well once I get the tune!

 

Is that all the bolt ons your going to do? If your going to do more work i would just wait it out. I don't think you will see 306 RWHP with that set up but it will be close. maybe 280ish

 

Not really sure of what else i should do...any recommendations?

 

Click on my IG see if you want to do that much work to your car. LOL! I did a lot and i pushing 430 RWHP

 

My work laptop doesnt allow me to view your instagram. Can you tell me a bit about your build? When it comes to internals i dont want to mess with that until im at a high mileage,(im at 75k right now). Anything else i can mess with to squeeze a little more power out? Im very curious considering your pushing 430 whp. Thats pretty damn awesome!

 

Stillen SC, light weight pulley, carbon fiber driveshaft, fast intention exhaust and HFC. Now I am at OEM cats and now have motordyne exhaust. I wanted to be at 2.5 in diameter that's why I changed my exhaust. And I had a smog check and got lazy to put the HFC back on the car so I sold it. I will redyno the car to see where I am at when I have enough ppl ready to dyno there cars again. I am at 72k miles right now.

 

Im assuming thats pushing around 7 to 8 psi? Yeah im not planning on boosting that's too expensive considering im still paying the car off. For now just these few bolt ons just to mess around. Later on ill consider it though! By the way where did you get the carbon fiber driveshaft from?

 

powertrain industries in orange county. 1st one to do that.
