Ok guys, so I have everything but the G5 programmer that is needed to get a baseline tune for AA. My question for someone is this.........I have a weekend here where I can change out the Intake but want to know if anyone did this and drove it a bit before getting the tuning done? Did you throw any codes or have an running issues? I am looking at another couple weeks before I get the programmer and probably at least a month before AA would have my tune back to me. I have to drive this car.

I believe you can ask that question on this thread. I think it's the original. Lots of pics of the job too.

Guys, I have decided not to do the upgrade to my 525xi. I purchased a 1931 Ford Model A Streetrod and would rather put the money into it. I have all hardware and parts purchased to do the upgrade except for tuning. The Intake setup with Adjusters already installed is from a 40K mile car and all plugs are still connected. I purchased the screws, tube, and gaskets from BMW. I will sell all as complete ready to bolt on if interested for $900 plus shipping. I am located in Iowa 50007, so when figuring your shipping cost use your zip code and estimate 25# weight. Box would be 18x18x24.
If interested text me 515-339-9456. I will accept MONEY GRAM (WALMART) only for payment and ship via UPS or USPS Priority Mail with delivery confirmation and insurance.

Hi Guys, I have found an intake manifold off an 330i complete with valves. I would like to know if I can just fit this in my 523i 06 E61 and get the tune at a later date. Also would I feel the difference by just installing it on?

Hi , I have bmw e60 525i 2008. I live in Brazil , and would like to exchange your engine for a N54 . Many will say " buy a 535i " but unfortunately in Brazil did not go with the 535i e60 body . The idea is to buy full engine wiring harness , engine module and CAS . They say the problem and make the systems talk to one another . if anyone can help me follow the vin number of my car WBANU51069C010000 .
thank you
thank you

I did this on my 528xi about 10 months ago. I have an OE Tuning tune. No local all wheel drive dyno, but my butt dyno shows way more torque. There is a write up on this for a 325 by member e90pilot on e90post.com/forums - it is actually a sticky on top of the normally aspirated section. He now has the AA tune. I did the manifold swap with a buddy who is very mechanically inclined in about 3 hours. Less parts are needed with the 528, but still straight forward. Good luck...
how much did this mod cost you, I have a ‘10 528xi looking to perform this mod

I am always suspicious of dyno test shops that can't even give torque numbers using the proper nomenclature. Torque is given in lb-ft, not ft-lbs. Ft-lb is work done, not torque. Also, the "butt dyno" is very unreliable and really shows acceleration, not torque.
