Default VF engineering tune

Just ordered a VF Engineering Tune for the 997, really curios how much I will notice. Anyone have a tune form them, would love to know others experiences with them?

What other mods do you have? From what Ive read, you'll need to have intake, throttle body, exhaust, cats, to have the tune make the most power for your dollar.

So far this is the first mod, other than cosmetic and a Gundo hack exhaust... I have friends with VF products on their R8's and Lambo's, all with great feedback but those were for the superchargers. Next step may be the supercharger, but one step at a time.

Yeah, I wouldn't anticipate too much of a gain from just the tune of a NA engine.

Reading their website they advertise 24whp/23trq, which is pretty significant and more than any other company advertises from a tune. I am definitely interested in your feedback as I am looking at a tune as well.

Fedex says it arrives tomorrow, I will let you know how easy it is to install and how the power gains feel. I don't have access to a dyno but I have a pretty good feel...Stay tuned

Interested to hear the results. If you dont have sport mode I think at the very least it will remap the throttle making it feel more punchy.

Ps - and definitely keep me posted on the supercharger plans :-)

If you take that next step to the supercharger you will get a bunch of good info from searching RL member Petza914's posts. He has a RUF R Kompressor on his -05 997 and has a wealth of knowledge on those kind of mods and all aspects of Porsches in general.

Yep, let me know.




Interested to hear tune results. I've never done a tune prior to other mods, only as the final step and as a Stage 2, like on my Cayenne Turbo S.

IPD plenum
Secondary cat bypass
Cargraphic muffler
HHR open intake
EVOMS billet diverter valves
Fabspeed Stage 2 tune
Added 100 HP bringing her up to 650.








Wrapping up a PCCB brake upgrade today.


See if VF will make you a deal on modifying the tune you bought before installing it if you add other modifications. Once you have the Genius programmer, it's just a software file on their end, then you'd be able to retune and optimize if you decide to make further modifications.

Curious to see how the tune works out as well. I have never done a "mail order tune before" I have always dyno/street tuned my cars. Curious to see how this works out for you.

I am also very curious to see how the tune works out.

I contacted a couple of places (softronics, GIAC, APR, etc), probably 5 in total, and all but one said there is no difference in sending them a base file, and then them sending the tuned file back and installing, over a full dyno tune. I forget which one off the top of my head, but only one said " yeah with the other mods you have, dyno tuning is the way to go"

the dyno shop I talked to (National Speed, Wilmington, NC) said they'd start with a GIAC tune for the base (lowest claimed HP out of all of them....) and depending how everything works together, they said they should be able to pull an extra 25-35hp, possibly more. but i'll believe that when I see it.

current mods on my 07 997 base:
Engine rebuilt by Vision Motorsports, included polished and ported heads, knife edged crank. (long story)
Fabspeed dual cone intake
Borla Headers
AWE 200cell Cats
Borla Mufflers

Upcoming mods
Suspension: Ohlin's R&T or similar
wheels: OZ leggera HLT, 19"
Girodisc brake rotors: need new ones, figured id go slightly larger without busting the bank on a several thousand dollar big brake kit (unless stock S rotors/calipers can fit, but I've heard that's a no-go on a base carrera)
ECU Flash or Dyno Tune.

Remember the hp/tq numbers are at the peaks, and not over the whole curves. You should get some decent gains across the curve tho.

for those that have gotten a tune.. how does it compare to just getting a sprintbooster to increase throttle response..?

i would guess a dyno tune is the only real way of getting the best performance.. not all engines are the same.. how can a mail order tune fit them all?
