pieter -
you may have even more power available if you haven't hooked up the VarioRAM yet. the 3.4L intake has a resonance flap that opens up around 4k RPMs. it doesn't exist on the 2.5L. your new DME can control this flap; it will add low end torque.

Hi Paul, Stroked and Blown and Insite..(It sounds like a band name...lol)
Thanks Paul,
The Top and the door locks does not operate, after the security module change, from the dash buttons either, that is why I think they are all linked to the security module on the European cars? I will have a look at the wiring diagram.
unfortunately I do not have the barcode tags, but I do have:
Learning code,
DME programming code
Remote control code 1
Remote control code 2........why 2?
Ignition lock/alarm system code
Imoboliser serial code
Radio code
Radio Serial number
Transponder code1
Transponder code2
Transponder code3...........why 3?
Imoboliser code.
Stroked and Blow...lol
The car is at another guy's place that is building an equal lengt exhaust system for me so I did not chck the park brake light, I will check it the next time I see my car, probably tomorrow.
Insite,
Yes I did wire in the resonance flap and it functions perfectly. with the 2.5 DME there was a hesitation around the mid range but now it pulls smoothly all the way to 7300 rpm. (before the 2.5 DME limited it at 6800 rpm)
The dyno say I have 180 hp on the wheels @ 5500 feet altitude asl. (Yes we all live here very near the clouds...lol)
Do you perhaps know if this is more or less what the 996 shows on the dyno. I know the engine is rated at 300hp.
Regards
Pieter

Ouch! Sounds like you have a pretty big tuning window still. My bone stock 2.5L is about 175RWHP at 1400' elevation. Only engine mod is a clean air filter and UD pulley.
... also the fast color: Guards Red.

he's at 5,500 feet above sea level. at one mile, HP for a normally aspirated engine drops by about 20%. he should be around 195 - 205 RWHP with that engine at that altitude.

Hi Kevin,
I was figuring a well oiled 3.4 at sea level to be about 260rwhp and at 5500' to be around 217rwhp. Here is my altitude calc: 5.5 x .03 x 260= 43hp loss. Lots of tuning room if he is only getting 180 now.

The remote does not operate the top.unfortunately I do not have the barcode tags (Remotes cannot be reprogrammed, they are worthless without the tags), but I do have:
Learning code,
DME programming code
Remote control code 1 Only a partial code is given here, these 2 codes cannot be used to program the remotes.
Remote control code 2........why 2? The car originally had two remotes
Ignition lock/alarm system code
Imoboliser serial code
Radio code
Radio Serial number
Transponder code1
Transponder code2
Transponder code3...........why 3? The car came with a valet key (no remote)
Imoboliser code.
