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!

@Ike, I sent you a PM with my tuners contact info, good luck!

I can confirm that the car goes really well, a bit smelly without the cats though, will need to address that.. Also for environmental reasons it doesn´t feel totally ok without.

I had the same problem - without cats it stunk. And without some kind of muffler it was deafening. I can send you links to what I put on mine if you want. They worked well.

One thing that is for sure though - make sure your exhaust tips terminate behind the bumper. Ever notice on old cars (pre cat era) those things stick out the back like 6 inches? This is why! (Learned that the hard way).

Also, VERY IMPORTANT - if you're working on the car, run a fan under the vehicle briefly before getting under there. The rear bumper acts as a bonnet and traps carbon monoxide since it's lighter than ambient air. I actually got CO poisoning because of this. It was not pleasant.

Well boys, now I know..

As stated before I had no chance to get a dyno reading. However last weekend I did my first track event with the newly mapped engine (And my new Hartech race sump, can tell all about that later)

I can confirm that for the first time I was totally even with the 996/997 carreras on the main straight. I also shared car with my father who ran in another class, he noted that the car defenitely had more power than at previous events.

How much extra? Wish I knew, but it´s significant.
