Interesting. So for the 2012 A6, 4th and 5th are equivalently spaced, there is no 1:1. Thx!

...confused

So .... riddle me this ....

I dyno'd in Phoenix at 105 outside temp Sat.
1st pull in 5th gear (by mistake) with a 45 min. cool down (which probably did nothing) hit 470hp.
Pull #2 in 4th only showed 420hp.

Tech blamed Intercooler temps at 215 for poor #'s ?

Which parts of this if any makes sense?

Stock 2013 A6 with Roto-fab.

Feeling I should be 470+ IN 4th. How concerned shoould I be? BTW NO intercooler issues as I went straight to dealer after pulls

thx ALL!

Glad I'm not the only one to get that feeling. I was expecting what I see posted here. Apparently most of these posts are on dynojets. The difference is pretty drastic.

First dyno run

Installed a RotoFab CAI on my otherwise Bone Stock ZL1 today and did before and after dyno runs. The rwhp jumped from 486 to 521! I was surprised to see such a big increase - I was expecting around 25 hp. The dyno trace is posted.
