EVOMS customer Power -is it real ?

EG if you installed a Motec system you need a base program to start the engine running to commence the specific fine tuning.From there you build on the data that you collect--both in intitial tuning(usually on a dyno) an d then in real time.This can be done on the run or from the data collected -- this can be ongoing. Often done like this for race cars.
The Motronic factory system effectively has that base tune-- that is modified and built on.Intially on dyno -- and in the same way you can build Motec program so it can be done with Motronic(by the few that can) .I presume that is what is happening with the more sophisticated individual custom engines and one of the reasons that cars are with programmers for some time.
The other category-- less sophisticated tunes that are developed in house with reasonable safeguards that are sold to all and sundry.Providing individuals are savvy and prepared to go to some trouble collecting data to send to programmer to verify the parameters are being met I see no great problem with that.
Using the Durametric system to collect data seems to be an acceptable way of achieving this--and also sending updated/corrected file to the ECU.
Anybody with a dispute of my summaries --please say so!!

P.S.Not trying to be a d*ck to anyone that owns a Ruf as surely they are beautiful well crafted machines rather I was just trying to prove my point that the Evoms car could not have been running properly(same for the Ruf)or driven properly(again same for the Ruf).

The owner is going to get the car checked out before we test it again but he seems to think it is running right but just has a bad mid range.....

I am a EVT700 equiped 997tt owner.I am not in US but NZ,same fuel grand as uk,I use BP 98 RON for street drive..
My car has extra mod beyond EVT700 are IPD plenum and cat-less exhaust.I have dynoed my car in local torque dyno,a NZ developed mustang system,very similer to mustang tech.I can't make that much power as the UK EVT700 or US evt700 showed.With BP 98 my car made 511awhp @1.3 bar,and with 105 vp unleaded race fuel my car made 538awhp @1.5 bar( in sport model).The dyno provider told me base on his system the 997tt awd trans should caculate as a 22% power loss.So my true engine power is 655hp with bp98 and 689hp with 105 race fuel.
I still trying the 60-130 run,just found the vacuum lane losing from the FPR,will get it reconnect next week and make a proper 60-130 run to provide the EVT700 power.The best time I had is 7.52 secs on a 4% incline road.
So this is pretty much what evt700 is.Remember I have 2 extra beyond the EVT700 package.So you guys have some probable ideas.

btw I am think to do a protomotive tune because my VTG turbo upgrade done by them.I have read some protomotive 700hp claimed 997tt did high 6's 60-130 but never seen an evt700 did below 7's so I holding my last try with proto..
I wish to get some nice thing from euro tuners all the time but just can't afford the price they offerd..Wife gonne kill me for that much money to make my car faster..So ye,US tuners are good for me : )

News Flash! This can and will effect performance.Reconnect and start over.These cars are tough if you don't have all your ducks in a row!

Something new to me regarding this discussion of US tuners vs. European tuners...
I have noticed US tuners are criticized in Europe for bolting on too much hp without doing internal strengthening. I noticed on the 9FF site that they feel it is safe to bolt on 670hp to a 997 GT-2 block without internals. Most US tuners say it is safe to bolt on 700hp before you need to do internal modification with is not much different than 9FF. There are some exceptions to this rule among US tuners I realize.

Hmmm,funny you mention Ruf for" Porsche power numbers",seems that RT 12 (650hp,i guess)that was at the Texas Mile was down a few ponies since it only ran 173 with a pro driver behind the wheel(Tanner Foust and it was on an episode of SE).Hell A GT 700 and EVT 700 both have 12 mph on the Ruf.(One of them ,the GT700 owned by MBailey,who is a member both here and 6speed, were run AT THE SAME EVENT as the Ruf)How do you explain that?.Surely if these Evoms cars were down on hp they would not have outrun the "Porsche power number" Ruf?By the way 12 mph is more than 50hp at the mile.

~0.15-0.2s but I dont make it into that crowd!
So it appears to me you could make it under 7s if you could find a level road and shift in 0.3s or better. BTW, you definitely need to fix that loose line on the FPR!
