The general concensus seems to be that re-chipping a 968 is largely a waste of time. Porsche seem to have got every last bhp out of this engine, and at best some of the chips might give you a bit more torque in the mid range, but ultimately no more power. This has been discussed at some length on the 968UK forum, as has the topic of improved suspension. Suggest you visit and have a browse through what's been already debated.

When I had my 968 I fitted an Autothority chip and found that mid range response was improved as well as rev limit lifted by 200 revs. Would doubt that I had any power gains but car felt better. With regard to having the ECU remapped this is a bespoke service for your car not an off the shelf chip. Whether it would yield the extra bhp against the cost involved is something that you should discuss with the likes of 9M. I had my 993 remapped by them and got over 30bhp extra.
As far as I was aware AMD are more up on Audi rather than Porsche.
Go visit 968UK forum as John has said before spending any money trying to wring out extra bhp.

Phil is pleased with the result as the car is a bit more responsive, and having been in his car it sure goes well, but the bottom line is that there is no free power to be found in a 968 by just changing the chip.

ooooh Sundeep -- please get your aspect ratio sorted on your profile photo or have you been playing with a fisheye lens?
Maybe he just likes driving short cars !

Performance "" no notable changes upto approx. 3500/3700 rpm, the rev limit is raised by 200/300 rpm.
From 3500/3700 rpm the car pulls more smoothly and with greater ease. There is a notable increase in performance during acceleration with the car "˜more willing' and revving with greater ease. The power does not appear to start to drop off until about 6600/6700 "" pulling from the 3500/3700 to the rev limit much better, more smoothly and with greater ease than before.
I expect that the power/torque increase is no more than mid to late single figures "" but higher up in the rev range the driveability is vastly improved "" well worth the change.
....and it performed well on my Trackday at Castle.

He has kindly given me a chip to test out. I got to the circuit about 8 and put my spare set of wheels on, after a briefing I found I had about an hour before my sessions started. After a bit of fumbling around and the odd dropped nut I managed the whole job in 40 minutes -- much to my joy it started first time (I am a chip change virgin!) and it idled very happily around 800 to 900 rpm.
Impressions are 2 fold.
Pick up in the 3000 to 5000 rev range seems much smoother and when doing normal road use, there is a sense of more torque and faster power delivery.
On the track I tend to keep the revs over 5000 rpm. This new chip has raised the limiter from about 6550 to 6950 according to my tacho. I am confident of the condition of my engine (thanks to Hartech) and am happy for it to rev to around 6500 for short periods -- it sounds good and very willing. Before the change the 6550 limit was a problem with some corners & gear changes but now I can use 6500 more confidently than before. It has given me the effect of an 'extra third of a gear'
That is enough of the subjective stuff -- I have booked a power run next Saturday at my local rolling road. Been there about 6 weeks ago so hope to get a fair test of the Promax chip. (yes I will ask if it has been adjusted or re-calibrated since)
So the final verdict for me will come in a few days.
