I was going to do that but there's really no point. Even if I found that the car is running lean, there's nothing I can do about it. I don't have a program to alter the fuel/ignition map. And I can hardly just tell Evolution Motorsports that I'm running lean at certain rpm so please increase the fuel at that rpm.

Like I said, I'm probably going to revert to stock and get someone to do a custom map on the dyno... Only issue is $$.

Thx for sharing all this info. I'm not sure if I was reading this right but is your max hp 238 at the wheels? A bone stock S would have about 220hp at he wheels give or take because of the difference between tip/maunual parasitic driveline loss. That's pretty good if that is correct. It would still be nice to have a bone-stock baseline, but 220hp is probably pretty close. I calculated the driveline loss and it looks like you are making about 273hp at the crank which is pretty respectable. Like you said though, the GIAC programming didn't do squat. It looks like the Dansk headers and cats alone gave you the hp boost and perform as claimed. Keep us posted.

Yes, from the dyno, it's about 238bhp now. Used to be 239 before the GIAC program but that 1bhp is probably negligible

My 'baseline' dyno with Dansk headers is 223bhp if I remember correctly. Wished I had done 1 dyno under totally stock conditions though...

Spoke to the person at Evolution Motorsports today. There's a full satisfaction guarantee on the GIAC program. I will just need to send my DME back to them to revert it back to stock and a full credit less shipping will be given to me.

There is no custom tuning services they offer. I did enquire about the possibility of having someone from EVO travel down to where I'm and tune the DME on the dyno but apparently, that is not possible.

Kinda ironic since if GIAC has a program to alter the fuel/ignition map, they would surely have the ability to custom each map to a car. Just a matter of cost. Oh well, looks like the end of the road for me....

Any suggestions will be most welcomed. There're a couple of pretty competant tuners here which I'm sure can do the job. Problem is getting the program to access the fuel/ignition map...

Sigh.... another week of living without the car again....

GIAC is custom tunable from what I understand. Obviously Evo can't do it without your car so getting your money back is a good idea. Did they offer any kind of guess as to why you're getting the results that you're seeing?

I believe there's a member on ppbb that has the exact setup as yours. He went on to dyno everything too and had much better luck. I think his name is Andy. You might want to do a search over there and talk to him.

Lastly, you might want to ping Garret @ GIAC. He might be able to offer some suggestions on where to custom tune over there or give some insight as to why you're seeing what you're seeing.

Nope, the person that I liaised with, Mike Myers, was not the least helpful. He said that there's nothing that can be done and there's only the various off-the-shelf program for various stages. No offer to explain. He even tried to pull a fast one by telling me he warned me before I wanted to get the GIAC program that there would be minimal gains considering what I've placed in the car already??!!! I 'refreshed' his memory by reminding him that he told me I could probably expect gains of between 5-10bhp since I'm not compensating for fueling with my mods.

Like I said in my previous post, I even offered to pay for someone to drop my Singapore to tune the car on the dyno but he said that was not possible. No offer of explaination of why there's no gain was offered either. Just told me to send the DME back and get a refund, less shipping.

Honestly, I'm pretty disappointed with Evo's level of service. I had to call 4 times and each time was told he's busy. Left messages 3 times for him to respond to my email. Email was sent before that with no response. Wasn't really expecting this kind of response but what the hell, at least I'm getting my money back.

How do I get in touch with Garrett? I did try writing to GIAC using their general enquiry email off the web but the response did not help. They basically said they did not have any program that cater for a sports cat in addition to the header/muffler/intake setup...

Well, it sounds like you've exhausted (no pun intended) all options as far as Evo and GIAC are concerned.

There's 2 places here in the Bay Area that deal with Porsches and tuning them. Akkurat and Dynospot. You might want to call them and see if you can get some kind of guess as to why you're seeing what you're seeing. It's worth at least the phone calls.

Again, try to ping the guy on ppbb that has your setup and see what his story is...as I remember everything went smoothly for him and he got significant gains.

But other than getting someone to dyno tune your car on the spot, I don't think there's any other options. Good luck and keep us posted.
