pics - dynos - TII & vert - similar to yours??
Wadda ya think - is the powerband shifted from exhaust, boost, & old S5 turbo or is that normal for a TII?
(18% added for bhp)
.
(Notice the MPH 4th tops out at between the TII & vert)
.
.
Is this about right for a NA ?
165hp for 104K miles isn't too shabby for OEM exhaust piping
I really should do intake next as I've noticed cool nights add ~10hp, so more cold air would definitly help. I am getting 18/24 so I'm loving the fuel economy.

sounds pretty good, there was an s4 recently that just had intake and exhaust @8lbs and ran 185 at the rear wheels, so that doesn't sound too shabby. hey look at my post in the 2nd gen forum about what time i should run and give some input please.

Why wouldn't thay have engine rpm as one of the axes??
Seems like it would make things harder to tune....
I don't know about the TII graph, (wow, tons of low end tourque) but the N/A one looks about right, except I didn't think tourque would drop off smoothly and slowly like that, I though it climber up pretty steadily, then dropped around 1000K before redline.... usually a freer flowing exhaust opens things up a bit up high like that. Oh well.
What's with the spike near the start of the TII dyno graph?

For the NA I'd imagine the OEM 2.5" piping and/or OEM intake is a bit restrictive. So mabey more low but less top end torque by keeping the OEM piping/bends (but adding downpipe, perf. cat, & mufflers).
He's got my graph saved on the dyno computer, so mabey he can add rpms. I'll ask next time I'm up there.
The TII spike is turbo spool up from 3rd to 4th. He records in 4th only.
