Now for some random comments on things throughout the day:

1. This is for Scheides' comment above regarding the 3port and AP. Kracka thinks that the reason why the gains are so drastically different is because the 10's ECU just DOES NOT like MBCs. He told me that he fiddled with boost, timing, etc and he just couldn't make it any better.

3. As for MAP's o2/dp, there needs to be a slight tweak on it. The o2 bung needs to be moved to the original location. The place where it is now is not very good. Here's some pictures.

4. Now I fell asleep watching TV ~10pm and just woke up and found that this thread was posted (along with a text from Kracka). Having read and looked at the graphs and having the adrenaline high wear off so that I'm thinking more clearly now, I'm not sure if the o2/dp is worth it. Don't get me wrong, I love that it made gains and I was just as excited as Kracka to see the results, but we need ONE more test to see what the real difference is. Hear me out...

Discussing (well listening on my part) with Chris@Cobb about the o2/dp, Cobb says that the restriction is not the o2 housing but the downpipe portion itself. That is the reason why Cobb only makes the downpipe section and not the entire o2/dp. Looking at the gains between stock o2/dp vs MAP's o2/dp, I wonder how much is actually provided by the o2 eliminator and divorced design. The gains are small enough to where going from the stock downpipe diameter of 2.5" (or whatever it is) to a full 3" MAY BE the difference that provided the gains and not necessarily the o2 elim part. MAP's o2/dp does have a wider diameter downpipe as well and the whole thing really is a 3" pipe from turbo outlet to testpipe flange. However maybe the o2 housing bellmouth flows just as well given how it was designed. Just something to consider. Maybe Cobb DID do their research correctly. :) Thoughts on this?

Perhaps Chris@Cobb might be willing to do another super awesome deal to someone willing to lend their car for some testing. Hmm...

Just to share, the AMS o2/dp addition on my car, required a a bunch of retuning as well to keep the boost control in check.

You should have seen the amount of black smoke that poured out of the car on the first pull with the o2/dp. The dyno room was in a haze and so was outside! I definitely wouldn't install one on a car without a retune.

Even if the results were equal I'd still do the o2/dp. The stock housing weighs a ton.

The stock o2 housing specifically must weigh 30 pounds itself.

Overall I am just pumped you have the car to a whole new level.

weight comparison
stock o2 housing & downpipe: 14.8 lbs.
MAP o2 elim dp: 8.2 lbs.

I also popped a CEL (P0140 - rear o2 sensor) on the drive home and within 5 minutes Kevin/Calvin had a new ROM in my inbox...not too shabby considering it's Sunday and the Cowboys game is on.

BTW, they're installing E85 pumps at a station that's on my way to work. Not hinting at anything, just sayin' ;) If my stock fuel injectors/pump could support E85 on my current setup it could be fun having alt. maps.

It's also impossible to switch back once you've had E85 on stock turbo. The torque is a drug.
