Swapped out my FI HFCs with test pipes and updated my OSIRIS with a dyno tune at UpRev and only gained 6HP and 6 ft/lbs of torque.

I dunno, thought I'd gain a little more, at least 10.

Just FYI, it seems FI HFCs are highly efficient.

do you feel a difference in driving?

NA gains are generally about what you saw. On an FI motor though, the gains are much greater.

how did the low/mid range look?

mid to low were pretty much even as before, there was a jump in peak somewhere around 6500 or so. Didn't get a dyno print but they should be emailing it to me.

And yes, after Jared at UpRev tweaked it for a bit the car feels much better. It has much smoother accel. now. AFR is very happy after 4000.

Where did you get your tune at?

Im FI and i got 23rwhp and 31rwt out of my set of test pipes but im really getting sick and tired of the smell.

Sound clips please!

6 HP is actually good (and is what is typically expected) if you also tuned the same way with the cats.

OTOH If this was your first tune, it throws any comparison out the window.

A tune should typically gain around 10+HP.
