Shawn, tq dropping off is most likely from two things: boost pressure dropping, and flow-restriction...

The boost dropping off has already been noted.
Regarding flow-restriction, the first place that I notice is you are still running stock exhaust, which was designed for a ~200rwhp car!

Rogue - As always I appreciate your input. I am running a test pipe which is definitely less restrictive but even so your right that I am pushing it , I guess I am trying to get a feel for component limitations before I upgrade.

I am thinking of trying to fix my drop in boost pressure (WG spring, EBC) and see how it looks. Then I will start attacking flow-restrictions and then possibly some timing tweaks.

It is great that I have a dyno a few miles away and that it is only $50 on Thursdays nights. It makes it easy to test different mods and it is also a lot of fun.

Yep, it is nice to be able to quantify each individual change... Then you truly know what was effective or not.

I'm assuming this kind of upgrade requires at least a dual port wastegate?

Did you pick up one of those 2.75" downpipes from the group buy? I dropped my car off this weekend for the head refresh and 27/6 install. Hopefully I'll have it finished by late march and will be posting new dynos. The one I use is less than a mile away

Zeff - Still running the stock down pipe. Cool about your car, lookin forward to seeing the results. Those mods along with what you have already done should make for a very fun car.

Pffffffft NA's I thought we solved their problem long ago... Just buy a turbo just kidding...

P.S. If I don't respond soon I've been killed by an NA owner, I just ask that I be buried naked in a carboard box and funeral will be open casket.
