US vs German vs UK 997TT tuners
... in the latest (April) issue of 911 & Porsche World magazine.
9ff
EvoMS
DMS
Cargraphic
Revo
interesting test, GPS'd accel runs down a runway. same day, same driver.
now one-day group test could be improved, but its nice to finally see an independent instrumented test of tuners from both sides of the atlantic...
anyone here know some of the cars involved?
sorry if a repost

The EVO one is the one with the Martini stripes, GT2 add ons, very pretty. I think it is full weight compared to others there especially the Cargraphic one which is super light @ 1480kg/3262lbs....
The accompanying text seems to hint at the EVO one having lower torque than the others despite the dyno sheet below (which is from this car) showing some ludicrously high numbers....
It would have been good for the article to have expanded on how the cars actually drive, it seemed that the 9ff 730hp car was devastatingly quick but had massive lag and they say the EVO one seemed to "lack torque" which may also mean lag ? or just an on/off power delivery ? Anecdotally I was told that the EVO car was slower than a stock 997 GT2 on the straights during a track day...
The Cargraphic has a massively expensive RS Tuning engine so it SHOULD bloody well perform - they mention how "nice" it is to drive but I would like to have read a bit more about what this meant relative to the other cars since this is one area rarely covered and actual driving experience (ie smoothness of torque delivery, throttle response etc) is much more important than one car being 0.5s quicker 0-200kph than another....

there is indeed a suggestion of relatively less mid-range torque in the article...
"...what's clear is that it does enjoy a definite power advantage over the other cars-- 9ff TR-74 excluded."
"...although the DMS car matches it to 100mph-- perhaps a sign of the restricted mid-range torque on the EVT700, a theory backed up by its only average in-gear times-- the EVT then gets into is stride and pulls out a significant advantage by 150mph... it even starts to chase down the lightweight Cargraphic car. Remember that car had nearly a 1.5 second advantage at 150mph, but the gap has been slashed to just 3/10ths by the time they've reached 160mph. Once its up and running, the Evolution car absolutely flies."
On drivability:
"In spite of its performance, driving the EVT is still not a great deal different from the standard car. Noise levels are reasonable..."
"Its a pity, then, that under sustained acceleration a slight pulsing could be felt in the power delivery. Regal says this is the engine running close to the torque limits set by the ECU and that it is still working on refining the mapping still further, but it does detract a little from the smoothness of the power delivery..."

Nick's Martini-wrap Turbo had been described to me by my suspension tuner as 'rabid' when he did the test drive on it after tuning the geo!!
Nick though said to me that he's bored with the 700bhp already and wants more!

Alex, I guess the moot point is that the 624PS821NM (engine dyno) car was so much faster than the 725hp/1020NM (chassis dyno) does he really want more or just what he thinks he paid for ? (caveat being he paid probably half the price of the 624PS/821NM conversion)
