"I believe his claim based on my experience" is very different from "I claim x whithout driving his car" Just to clarify in case you are confused

Well, i did feel the difference and you didn't. It's all good.
Bav felt it and reported, happy ending no? I want to hear more details.
No need to force or over-worry about other members, since they are smarter than you think.

Nobody claims it was "investment", no argument needed.

Sprint Booster example I took is about people's reaction, was not chipping comparison. (FYI it has nothing to do with chip) So "apple to orange" comparison is your misintepretation.

No offense, but I'm more interested in Bav's experience than the redundant information that we saw every forum. Let him share his experience with us.
That's all.

I am gonna have a decision by Friday.


In fact, I think I'll take her out for a drive now.



I would only recommend the upgrade on the premise of there being a guarantee to return it.


And that there is...for ALL buyers. What's the big deal then?

I don't want to piss anyone off. Please take no offence as nothing I say below is directed at anyone personally.

I think aftermarket chips definitely changes the data map so that some values are different to factory settings. As to how much improvement this change offers, I think it's best to test it with things like the Apexi RSM or an accelerometer like the Tesla. I used to do back and back testing using those when I was tuning my MX6 turbo. It shows the difference before and after intake and exhaust mods very convincingly. The Boxster, being NA, would show less measurable benefits but should still be demonstratable nonetheless if the chip does what it claims. An Apexi RSM can be had for around $200AUD or a Tesla device for around $90AUD on Ebay. In many ways, these offer more real world measurements (0-100kph, 400m) than dynos.

I own both. And intend to do some testing myself when I start to play with the snorkel removal and header installation later on.

On the issue of chips, here are two articles on an interview with the director of Powerchip in Australia you may find an interesting read.

I read the whole interview.


Wow, that interviewer sure did ask him TOUGH questions. No mercy.




After driving my car today, I'm not sure what to think. I'm leaning towards asking for my $$ back because it just doesn't seem like a huge difference, if any.


Better throttle response I admit. Better in 3rd gear for sure (but for some reason, doesn't feel better in 1st or 2nd)



I'm leaning against it now...but I'll see.

Can't imagine that interview doing much for his business, can you?

FINAL CONCLUSION


My now good friend, arenared, PMed me and brought light to my predicament.


If you notice my descriptions...Loss in 1st and 2nd gear, torquey in 5th gear, fast in 3rd gear, it leads to one conclusion: There is a loss at high RPM.


I would have never considered this. I always assumed that the high end yielded the most gains.


I am going to return this product A.S.A.P.



Meeting a girl Thursday night and have an auto-x Sunday but Monday I am going to...immediately.



Thanks to everyone for your insight and thanks especially to arenared for showing me what was right under my nose.


I no longer recommend this product for a 987 if it is your only mod.


Sorry guys if I caused you trouble

Sorry to hear that your chipping experience did not work out. Just my 2 cents, I am very pleased with the chip I got for my 2.7L 2000 Boxster. I got my chip from the folks at Autothority Pitstop, who were very helpful dialing it in for my car.

The main thing I noticed after chipping was how much more responsive the car is at low to medium rpms, which can be seen by the very flat torque curve. I would recommend it to anyone that wanted a few extra hp (I get a little over 200 hp to the wheels) but a noticably more responsive car.
