Just getting back from the shop. For my 08 G37S, I picked up approximately 20 HP at the high end probably 5 to 15 HP at the lower end. Has a good deep sound, as well.

I have not had it tuned yet; maybe I will get around to that sometime this Winter.

 

Congrats!

Are the AF sensor readings accurate?

 

AF sensors seem to be fine; no check engine lights.

Enjoying this mod. A new sound and feel to the car, so I have something "different" without buying a new car.

Looking at the clutch for my next mod.

 

I was only asking because the AF plot is shown in the attached pdf, so was wondering if it was really logged

 

Not sure what caused that drop off on the first run. Seemed to work fine on the second run. I might see the guys from the shop at a meet tomorrow, if I can make it. If so, I will see if I can get some more detail.

 

LOVE IT!!!!!!!!!! Thanks for posting this! Definitely keep us updated w/ the tune!

Glad I could help you out Aaron!

 

Nice gains!

 

I did get a check engine signal several weeks back during a long trip. I plan to get a tune eventually, maybe this Spring.

 

You sure it's because of the cats? These shouldn't throw a light...

 

Do you have any exhaust smell inside the car even with the windows up? I have the RHFC but I did not get the exhaust yet. It's been a month since I put it on. I the way the car feels with it. It would be a shame to remove it.

 

What catback you're running ?
