: Cobb Tuning + MAPerformance = Dyno Proven Gains!

Lets see, where to start...today was a pretty damn epic day. I honestly don't think I've been this excited about car stuff in a LONG time.

Quick back story:
Ever since I got my X tuned back in July I haven't been real happy with it. It drove really well, perfectly smooth, etc., but it was really down on power (especially torque) compared to where it "should" be. What really made that apparent and when I realized I needed to do something is at the NTEC dyno-day last month; my car was getting owned by even basic stock intake/stock catback X's. AFR's were spot on, it took a little timing but not much, and I was just sick of dicking with it.

Last weekend we got the MAP FMIC installed, but yesterday was the big day. First I started it off by installing a Grimspeed 3-port BCS then limped it to Cobb Tuning staying out of boost the best I could.

Yesterday's plan:
1. Completely retune the car with an Accessport at Cobb Tuning - Plano
2. Install MAP o2 eliminator downpipe
3. Retune again for hard back-to-back data on the downpipe

1. Prior tune (stock FMIC w/MBC) vs. Cobb tune (MAP FMIC w/3-port):

2. Downpipe install (please note the care they took, covered everything possible to prevent scratching or damage):

3. Stock o2 housing & downpipe vs. MAP o2 eliminator downpipe:

SOLID GAINS!!! To those who say they're worthless on stock turbo/pump gas setups...eat it :)

I want to thank all my friends (especially Scheides and Rmondoh) for their willingness to discuss setups, and special thanks to Rmondoh for taking so many awesome pictures throughout the day! I'm sure he'll jump in here with more of his favorites. I also want to give a huge thank you to the entire crew at Cobb Tuning - Plano! Kevin for getting the video and charts ready so quickly, Calvin for working his tuner magic on my car, and Chris for his eagerness to help facilitate this Accessport Challenge test plus the back-to-back test with the MAP o2 eliminator downpipe.

This should be in the dyno section.

You got me excited. I haven't bought any car parts lately. I think I'm gonna start buying again. Lol. Nice car and thanks for taking the time to provide the information.

You're welcome, I'm a hard data whore and am always happy to provide it!

Fine by me. Mods, please feel free to move if deemed appropriate :)

Moved to dyno! Congrats on gains. I missing this gain 40-50 hp every 4-6 months game.

Kracka is right about that. I made him his own picture Set in my Flickr account. You can see all the pictures of the day here:

Here are some favorites though!

Nice! So are you keeping the AP tune? What made you jump the MBC wagon?

Yup, I'll be keeping Calvin's tune, the car pulls like train so I'm really happy with it. I switched to a 3-port since that's all Cobb will tune with, and I wasn't happy with my current tune and didn't feel like dicking around with it. I did some logging/street tuning but then it hit me I wasn't getting enjoyment out of it anymore and just wanted to drive the thing.

I will say that Calvin did a fantastic job tuning the 3-port, it is very responsive and has a nice smooth boost curve.

congrats...I really want to know about MAP porting of the stock exhaust manifold, i heard it is even better than buschur. With 3 port you dont need forge actuator anymore?

the dump will come in handy with a bigger turbo :)

Great numbers Kracka! Thanks for posting this. I'm looking at very similar mods when I'm done with what I want to do for now. I've seen everyone get between 340-350whp with that same set up. That's all I want for now

MAP's porting is the best in the business. I've compared it vs. Buschur and PPI with my own eyes. On the Evo VIII/IX the MAP manifold did beat the Buschur on back-to-back dyno pulls, that happened a few days before I left Minnesota so I was able to be there for it. They also used my IX as the test-car for their ported intake manifolds. Ported/coated manifolds is on my to-do list eventually too.

I've never run a Forge WGA so I can't comment, but Calvin did a great job tuning my boost curve with the Grimspeed BCS.
