Who belives in the IPD plenum

[Robert986]

Howdy! It´s been a long and frustrating road for me, during the winter I installed the following on my 03s:

-987 airbox
-987 MAF
-74mm TB
-IPD-plenum (From a 3.4 Cayman)
-New oem injectors (Why not)
-Ebay headers
-Testpipes
-FVD Sound version

The car started right up, but as expected it didn´t run well due to the larger MAF diameter. It runs well the first 1/3 of the trottle position but if I get on the throttle it dies. I had an appointment with a tuner two month ago to fix the MAF part and do the mapping, but due to an extreme amount of bad luck we never got it done. Very long story btw ;-)

Anyway, now I have found another tuner that will take on the project starting tomorrow, so if everything works out I will have my car back in working order on friday, then I will find out at least what my well calibrated but dyno tells me.
The new tuner has just changed location and I don´t think they have the Dyno installed yet so, I don´t expect to get any real numbers unfortunately.. However at this stage I just want to have the car back in working order not to miss the track days in June. Wish me luck! :dance:

I have the 987 box, but its not installed yet,..I will do the IPD and the 74 MM TB,.with free flow secondary cats with the topspeed exhaust this weekend..to see if that helps my 2.7 going to also try to complete the 3rd radiator mod this weekend too..but that's very optimistic Iam sure..LOL

Robert, all you need is a 996 tune. You can do this with a piwis. I don't know how much your tuner is charging but buying the piwis com box online is not very expensive and the software can be found with the help of Mr Google.

Ike, how does the PIWIS.com box online works?

I believe that the PIWIS is a Porsche service tool (pricey as well..) and also that you have to pay a no so cheap yearly subscription..

Could this be a Chinese PIWIS..?

Thanks a lot for the suggestion!

Anyway I just got a call from the tuner and the car is finally done!!!! After 1,5 days of tuning, he told me it runs perfect and pulls like a Carrera... Man am I excited.. One more note, he said that the mods I´ve made on intake and exhaust-side seemed to work out well together, very balanced.

Will pick it up tomorrow! will report back! :dance:

Ok, the car is back from the Tuner!

The bad part: It seems my emergency brake on one side has collapsed somehow, there is an evil scraping sound inside it, so I can not (should not) drive the car.

The good part: When the emergency brake for a short while stopped making those noices I took it out for a proper spin, and man it runs really really well. You know the old tale "Porsche cut the nuts of the Boxster not to compete with the 911" Well, the nuts are back, and this time it´s personal..
Seriously, it does pull stronger than before and the sound is glorious.. Dark low tone when cruising and angry GT3-ish when stepping on it at high revs. And there is no drone.

Tomorrow I will take a look at the emergency brake, or rather what´s left of it. Then hopefully I can finally get this season started. :dance:

Robert, I am curious. Did your tuner share with you exactly what he did and how he did it? How did he measure performance gains (dyno, street runs)? How did he dial in adjustments? What are your knock sensors (if still enabled) telling you about the setup? Do you have any EGT measurements? Any AFR measurements?

Curious minds want to know!

Also, did you wind up going with the colder dial plugs? (I think that was you who mentioned that, right??

Ike, must admit that I don´t know all details, but here goes...

Since they have just changed location the Dyno was still not set up yet, so I got no measurements unfortunately. He explained what he did and I guess I understood about half of it.. But in short I belive the steps where -

1) Set up a MAF transfer table to match the new MAF, this was the part most other Tuners didn´t want to get into..
2) He put a broad band lambda in the headers
3) One guy was driving the car while the tuner set the mapping, this took quite some time as I understand it to get it perfect.

I honestly have no info on the other details, after this long time I just wanted to drive the car.. if you want I can PM you the contact info, I guess you are more qualified than me to ask and understand ;-)

Thanks for the info Robert! I'm glad youre back to driving, it's definitely hard to watch sunny days go by without letting the top down.

The MAF table is definitely the first step, followed by smoothing out idle and then building from there. If this guy really built a MAF table from scratch I would love to talk him!

Anyway, I'm happy you're driving again! Have at it brother!

Do you have a part number the the 74mm throttle body. I am struggling finding the correct one.
