"now where to find another 100hp.... "
Do you have an X pipe and Hi-flow CATS (or CAT delete)?
Also may want to borrow an AFR gauge w/ a wide band O2 and see what the numbers are, easy with an X pipe to add another O2.
It's odd that it is flat before 3k RPM, is this an Auto?

Test drive
Ok so I'm very impressed. Took a spin -pun intended- just now.
Either these chips are a present from heaven or my 928 was not running correctly before.
Now my 928 pulls till 5k( that's when I backed off), chirps my tires in second, spins off the line, and growls the entire time.
WHAT I THOUGHT A PORSCHE SHOULD FEEL LIKE!
i thought I was doing a 0-60 blast, when I looked at speedo, I was north of 90.
Holly cow. Glad wife's gone for another day. I've got 15 gallons of 6 week old gas I've got to use up.
Time me for another spin.

My next 928 will be an 85-86 32V auto and I plan to do Porken chip and X-pipe. I've owned a couple of 5-spd 16V LH euros and while they are certainly quick, I'd love to have all that S3 torque down low hooked up to an auto trans. Pure GT.

My perspective is skewed, but I love the hell outta mine. I am doing an intake refresh right now, and fitting all the necessary items for the Porken S300s chips. I don't have an X-pipe, but I do have an early Devek H-pipe, no cats, and an RMB.
Go S3...

Just got got back again. Played with a Spyder Boxxer through some 60mph corners, then we got a red light. It's a 2 into 1 merger after that.
Got him off the line, beat him to the merge area (about an 3/16 of a mile.
Now that's fun seeing a new Porsche in my rear view! I didn't even think he was trying till I looked over my shoulder and saw that 911 looking head light beside my 32 year old car passenger door.

Keep in mind the drag racer's creed:
"Engines run the very best when there is aluminum piston material being "metal sprayed" into the exhaust port."
Never, never attempt to tune at WOT without a wideband!
Porsche LH chips were designed to be on the rich side at WOT.....not because they were stupid.....but because they had to ensure that their engine wouldn't "melt" as pieces deteriorated (MAFs get lean as they age. Injectors spray less efficiently as they age....very rarely do they deliver "additional" fuel as they age.) You install a "leaner" chip to make more power, you must find out if it is too lean!
Porsche EZK/EZF chips have conservative timing....Porsche had to ensure that if someone got a funky tank of fuel, the engine wouldn't melt. You install a chip with more ignition timing to make more power, you better make sure that your engine can tolerate that additional timing!

1963 Pontiac Catalina SD 421 'Swiss Cheese' with the optional aluminum cast exhaust manifolds. Good for 1/4 mile runs ONLY. Otherwise you have little droplets of aluminum on the ground under the vehicle when you stop...
It is my understanding that S3 928's need more fuel on the top end if they are to be run hard.

More tuning needed

I love the way Ken's chips run in the S3 cars at idle and partial throttle. He refined his chips that almost every single S3 can benefit from a set of these chips. Generally a HUGE improvement!
I'm frightened the way his chips run at WOT in every single car I've installed them in.....way too lean and way too much timing. Every car I've used them in needs the two jumpers hooked up, minimum! Most need an additional "pot" to deliver more fuel. Some need a more conservative EZF chip, as some engines simply can not tolerate the amount of timing he added.

Tuning anything (that is going to be run at full throttle for any length of time) right to the "edge" is a bad idea. One injector sprays a little less fuel and you have a disaster. Smart tuners (doing tuning on individual engines) will find the edge and then back everything off a certain percentage. Smart tuners making generic chips will find the edge and back things off a bigger percentage.....to compensate for unknown engines.

Best to take Greg's advice on anything-he-does-not-make with a bag of salt!* 
Do not plug the EZ single plugs (green wires) together! This shorts the air temp sensor and will make the car a dud. My S3 chips were conservatively tuned for 89 octane.
It is good to verify your installation with a wideband O2 if you are going to run at full throttle extensively, but most folks do not. Plugging the LH plugs (brown wires) together will enrich WOT somewhat (S300s chips only). I no longer make the WOTpot, but it is not difficult to put together and install.
(WOTpot installation manual)
* It is difficult to realize unless you have dealt with him for a long time, but besides having a classic narcissist personality - a la the POTUS, he really doesn't know much about things he does not know about. He's quite functional, but when it comes down to it, he will make things up lie, then promptly forget/deny that he did. It has taken years for me to teach him just the basic theory about how the timing belt operates in motion.
Among his many sins is running a S3 with obvious fuel delivery problems on the dyno, then blaming my chips, etc, etc.

Leave it to Ken to come out calling me names, instead of reading what I've said and paying attention to what happens in the real world....
So, Ken, what part of what I say makes me a liar?
Is my statement that virtually every '85/'86 928 would benefit from a set of your chips (as they make the cars run much better off idle and in the midrange) the lie?
I'm promoting your chips, but encouraging people to check the mixture at WOT.
What part of that is a lie?
For those that do not know me and know what I do, I work about 60 hours a week, usually 6 days out of every week....working only on 928s. I'm crazy busy. I am mostly a problem solver....928s come from all over the world for me solve various problems. I build dozen of high output engines, every year. I know how to isolate injection problems. I know how to tune these engines. I have my own, in house dyno. I can read printouts from a dyno. I know too rich. I know too lean. I know too much timing.
In short, 928s are what I do.
In this thread, I'm just reporting what I've seen and what I have had to do, to make these particular chips function.....to help other people that are installing these chips.
Apparently taking about how good something works, while simply noting any shortcomings now makes someone a Narcissist and a liar....whatever.
Here's the reality:
I've installed six sets of Ken's chips in '85/'86 vehicles. These chips run great off idle and in the midrange, where most people spend 95% of their time. Every set of these chips I've installed were too lean and some had too much timing at WOT (two were dangerous). I had to compensate and add additional fuel on all 6 engines. Two of the engines, I had to remove timing, by using a different EZK chip.
All I'm saying in this thread is to not blindly install a set of chips that are tuned right at the very edge of engine damage, but to put a wide band on the engine and double check. If you have to add bucket loads of fuel and the mixture doesn't seem to respond...take timing out!
To not check is a recipe for disaster.

oh my, hurty feelers... how could anyone think ill of poor lil' Greggers! Fueling on the dyno is different than on the street. I tested WOT for months on the street and through hundreds of dyno runs. There any number of problems that befall a S3 in a static environment as the computers are 'dumb'. Many of these can be mitigated, but Greg refused to listen (or acknowledge them if he did them) and continued to run customer's engines lean without sorting out pre-existing conditions. Because: narcissism.
If the engine can't handle the timing (which is often lower than stock at WOT) then check cam timing, fuel injectors, fuel delivery, etc. Sometimes the chips just won't be a good match if too far from stock.
