Anyone with dyno results for COBB stage 1+FMIC?

I have been using this map now for a bit and I like it alot. I am using the stock throttle with it. But just wondering if anyone has had the chance to get on the dyno with the stage 1+FMIC? If so how did you make out?

Picks up some good power in the lower rpms but loses it up top. COBB is still analyzing the log files...

Thank you for the graphs, I appreciate it. Does look good at lower rpms but like you said kind of cuts off. If you dont mind keep us informed as to what COBB says about the data logs.

your right lol. I was throwing the idea around of gettin DPs but I just dont know if I want to deal with the emissions issues and all. Its kind of a pain here in PA. I was going for the VRSF DPs because of their affordability, but just havent been able to pull the trigger. Still deciding if I should get them or not. I also ran into some other car issues which I had to put out some cash to have fixed so money is a little tight right now. But Im thinking DPs would be nice....

COBB called me today to say that the datalogs all look good and show no issues with the car.

Like Skim7x said I need to get downpipes now Hopefully COBB will have their downpipes ready soon then I can get the Pro-tune at the same time and see what that gives me

So Cobb is saying v301 stage 1 no FMIC should make more peak power than v400/401 satge 1+ ? That makes no sense. There should be no good reason why it would make LESS power with a stock FMIC than with a better aftermarket one, and that should happen at both low RPM and high rpm.

Hope to hear Cobb chime in on this, they had promised their own dynos of stage 1 v301 vs stage 1+ v400 when they first released it.

edit: at the very least it should look like the two TQ curves spliced together, V400/401 down low and your V301 up high.

Same set up and still iffy about DP's too...Emissions in NY.. If cobb can find a way to set readiness then I'm in. I don't wanna go through the whole bms dp fix...and drive for god knows how many miles and whatever speed (impossible) OR have to keep swapping them every time (I have an xi..they are a bitch to remove). The CP-e ones are in the checkout cart but I'm holding off untill after I get inspected in june

We need a better solution!!

And I don't know what cobb is talking about but stage 1+fmic v400 feels MUCH faster.... butt dyno approved!
