Honestly, you can do all these mods with headers, 100 or 200 cell cats, ECU re-program...blah blah blah and spends thousands of dollars and not feel much if any bang for the buck on the street. If you are an experienced track driver you might feel a little difference or maybe .5 sec better lap times.
As far as car mods go...a lightweight fly wheel makes a nice difference and then suspension work. Put on some nice muffler for better sound.....but......
If you really want to car to go faster...spend the money on DE's and proper coaching and then when you get a point by from a GT3 at the track when you are driving your 997 you know that was money well spent. It's not about the power...it's about braking and balancing the car...

So many people here debate PDK vs 6 speed; S vs base, AWD vs RWD, mods vs stock....
but no one can debate the fact that the best advice is to make yourself a better driver.

Anyone know of a mod that will re-map the throttle pedal input sensitivity? I know that Vishnu makes this for Audi and JDM cars- Basically lets you get a more sensitive pedal. I'm happy with the speed / power, and as mdrums mentioned, it is more about knowing how to drive the car than adding 10-20hp.
The only complaint I have, and that I'd like to get rid of, is the input delay on the pedal. There is no "blip" with the egas, it is more of a "mash and wait", and it blows for trying to rev match on downshift. For comparison, I tried this recently on a manual Z06 and the throttel blip / response was spot on, almost like a cable driven throttle.
I got it straight from a porsche tech that the computer does not do an initial 1-1 input to throttle response when the egas pedal is initially tapped, it is sort of an input curve and the farther it is depressed the more the input becomes 1-1. His thought was perhaps it was designed this way so soccer moms or elderly execs would not put the 911 through the garage wall accidentally when they tapped the gas pedal. LOL - who knows..
I also get an occasional engine ping when blipping the throttle- don't know what that's about but it's been there since the car was new- and has remained even with aftermarket air filters, exhaust or with everything completely stock. Anyone else have this experience with their NA car?

to work on a car and treat it as an x-mass tree that gets more and more toys hanged on it is easier than to go and drive it on track or AX. plus when you look at big cost items like porsche schools or skip barber - it takes a real commitment to invest into 'yourself' instead of dumping money into any prized tin bucket on wheels.
to OP - if you got AWE headers/cats - do softronic flash to 'top' it all but stop there with drivetrain mods. and God forbid you to 'bolt on' any BS 'boosters' on top of any of your stock sensors - throttle, etc. do not mess with it.

When you do exhaust/flash you "lose" hp/tq at bottom end b/c it moves them and the gains up the power band. Most flashes increase throttle response and sprintbooster does it a lot. More throttle puts you in the sweet spot qicker (so does LWFW). So if you have full exhaust then flash or sprintbooster can help with the 'Loss" at the bottom.

So true...but there is a certain satisfaction when you catch a superior car coming out of a turn which certainly makes up for allot

FYI- I bought and installed a Sprintbooster (GMP had the best price, fast shipping as always). Had it a few days now. Build quality of the part is marginal, but it does work as advertised. Excellent remap of pedal- Am using 'green' mode for daily use. 'Red' mode is a bit touchy. Fun, but touchy. I highly suggest this upgrade, you can really feel what you were missing with the OEM pedal mapping. Makes the pcar feel like you just gave it a double espresso 
.
However.... The bog / ping on blip is still present. I'm hoping there is some way to get rid of it but as of yet no solutions... You can hear the TB sucking air when blipping but instead of that crisp engine response it bogs / stumbles, and gives the occasional ping.

Sure - You can get it through GMP or Vivid here on the 6. I wrote a full review of it here: https://www.6speedonline.com/forums/...-response.html

LWFW, AWE Cats, VF-E SC (modified) and a wide rearview mirror so you can see the faces of the drivers behind you. Get coilovers to get through the twists better, and brakes to slow you quicker, and you'll have the ultimate package.
Or get a GT2 and lots of DE.

The sprint booster is just a throttle signal multiplier. You would get the same effect by just pushing the pedal farther with your foot. It doesn't actual reduce the inherent lagginess in the Porsche ECU. (I believe the Porsche "sport" button is the same thing, though).
I believe this is the issue with the gas-save timing advance in the stock ECU. Generally it's bad practice to go from very slight gas pedal to a big helping of gas.

Contrary to what the loose assumptions are on the internet, Sprint Booster responds based on your throttle input, not a preprogrammed amplification. Anyone can step on a pedal / mash the gas. But there is no precision to that, and at the end of the day. You shouldn't need to do this.
We spent years calibrating the product to provide the response the car "Should have" straight from the factory. Company has invested the time and effort we have developing a plug and play modification that this type of effect on your vehicle. This is why we patented the technology.
The best way to sum it up is Sprint Booster is very similar to that "wired" throttle control from a decade and back. Many of our customers tell us that is what they missed all these years. The throttle response that was crisp and 100% there. When they need it.
We challenge everyone to try Sprint Booster. Purchase it from an Authorized Sprint Booster Dealer or purchase it directly from WWW.SprintBoosterUSA.COM . If the product doesn't blow you away, OR...... if it feels like something you can do by just mashing the pedal. Then document your experience from start to finish and publish it here on the forums. We welcome all feedback. But we are very confident that our product will impress you.
