Completely stock head except for cams. Yes the ECU is controlling the TVIS. We have the ECU open the TVIS at 3500 and close it at 3000 because we ran out of time. We want to go back once we upgrade to a CDI to re-tune and find the right spot for the TVIS opening point. The way you do it is you do a pull with the TVIS disable and another pull with it enable and overlay both dynos torque, and right where they intersect should be your opening point.

At that amount, did you have to pull any fuel out of the tune or do you just let it go a little rich?

I'd be curious to see the dyno plot with AFR and MAP graphs as well if you have it.

Not really, you don't star to see major changes up until around 700cc.

What HP did it make at the wheels? Did you log Boost VS RPM?

Were you able to advance the timing at all with it? Or did you tune w/o it and then just use it to cool the intake mix and provide a little extra safety?

Yes timing was advance conservatively.

OK quick update. I contacted the Dyno/tuner to request a Boost, RPM, whp,wheel lb torque graph and I was told that the Dyno actually reads wheel torque and whp, but it was displaying it wrong. He has since got an update for his Dyno and now it reads correctly because a lot of customers were complaining about it. I trust his word since he is very well known and trustworthy, but we still wanna go back and do some more tuning, once we do I'll post the graph.

Any updates? Why aren't you revving higher than 7000 rpm?

Car is in storage for the winter. We are going to upgrade to a CDI and rev higher and Dyno tune in the spring.

Not sure, the turbo as well as the manifold came from Full-race. Garrett GT3071R Twin Scroll Turbo - Full-Race.com I think this is the one.
