Congrats. You have to be very happy with that dyno tune.

So what about a different head design AND cam work? Forgetting now which heads are much higher flowing...ej20k?
Not sure I'll mess with anti-lag.

If I do different heads, then I have to redo the entire intake manifold and I really don't want to do that. If I do anything further, I'll do some work on the stock heads & cams.

Link does have the ability to monitor the knock sensor, and I can tune with that. The stock knock sensor doesn't appear to output the best into the Link. I'm working on upgrading to a newer knock sensor which has a better data output.

I will note that the G4 knock detection system doesn't work exactly how it should. It is not closed loop and doesn't pull timing UNLESS the PCLink software is connected. The G3 is closed loop. I have been told that Link is in the process of updating the firmware so the knock detection on the G4 is closed loop and reterds timing without the PCLink software connected.

They originally did this because they wanted people to use their knock block with the G4 ECU.
Damn marketing!
With a handle on knock threshold, you could definitely tune closer to 'the edge' and make more power.

Oh yeah, you don't want anti-lag if you like your turbo. Its pretty much useless on a steet car. But I'm sure you already knew that.

Yeah I was a little cranky when I found out about the knock detection not really working.
