First Dyno Run

So I finally decided to take the car in to the Dyno before I mod much more. I am pretty happy with the results.

Run 1: "Baseline"

Procede Map 0
Catless DP's
AFE DCI
87.29*F
51% Humidity
29.96 in-Hg

Run 9
Procede Map 2 15.5 psi
0% ignition correction
110 octane race fuel
Catless DP
Stock IC
Stock Exhaust
AFE DCI
Hood Open
88.36*F
52% Humidity
29.96 in-Hg

As you can see in the Dyno and on the log, a little over 4100 RPM's I had a big timing pull (either knock or the DME reacting to the high IAT's). My IAT's were going through the roof with the stock IC, so when I get my new IC the graph should smooth out a little bit. Overall I am pretty happy with everything.

No kidding! I want it, just trying to fight the mod bug. I usually lose that fight, but I have held off so far. I should be getting my new FMIC sometime in the next 6-8 weeks, and we will see how long that holds me over for.

Crazy IAT. You might want to consider meth before an FMIC. Better charge cooling and more power. And easier/simpler to install.

Your AFR is in the 13s at redline. That sorta scares me.... Time for a rev 2.5 upgrade.

The probe wasn't reading well on the dyno graph, but I do agree it seemed to be running a little lean throughout the run. The log from the Procede was showing slightly richer than the dynojet, but not much.

EDIT: I just added the AFR from the Procede log

I may end up doing that. I haven't completely decided yet. I know I would get a lot more benefit from Meth. If I change my mind soon, I'll be giving you a phone call.
