DLL: 422whp and 368wtq, not sure on the accuracy of this...
So I was messing around today, loaded Tephra v7 and wanted to make sure that everything was working alright. In the spring I had 365WHP and 359WTQ @ 28PSI running E85 with a my stock IX turbo at DB Performance on their Dyno Dynamics. Anyways I went out and did a couple pulls, then I decided to try out DLL...
The HP seems a bit high, but the TQ is pretty close to what I was making in the spring. here are the results, still running E85 at 28PSI. --
Engine Mods --
AMS Front Mount Intercooler
AMS Manual Boost Controller
AMS Polyurethane Front Motor Mount
ARP Head Studs
Cosworth M2 Cams
Cosworth Head Gasket
DC Sports Downpipe w/ Cat Delete
ETS Intake Pipe w/ Perrin Filter
Greddy Ti-C Catback Exhaust
Megan Racing o2 Housing
Nisei Intercooler Pipes
Nisei Mini Battery Kit
PTE 1000cc Injectors
Walbro 255 Fuel Pump

It's pretty accurate when you use accurate inputs: make sure you have the true weight of the car, gear ratios, cD, and a level surface w/ minimal wind when you do your logs. Not sure how you edited the run, but I'll usually show the full slope of the graph where the power starts to fall off later in the RPM range. I've noticed if you cut the run off prior to the power dropping it will show a much higher HP number.

I did change the gear ratios and the weight was pretty close to what my car weighs with me inside it. I'll mess with it some more this week and start the logs at a lower RPM.

That's a really bizarre torque curve. I've never really scene one that just continues to climb, especially on the stock turbo. Typically it will make peak torque at 4000 RPM or so and then fall off. I'd try some more, start logging when you start the car and make some pulls. Then isolate the pulls for the DLL shots.
Here's a more typical curve....
