Questions for Chip Upgrade Users
 

I know the consensus is not to do any mods on the Boxster as there is only marginal gains from mods. But questions for those who actually did the Chip Upgrade.

1. Which chip did you go with and how did you decide?
2. How long ago and what's your experience so far with performance difference ? (one manufacturer claimed 21hp increase, but only at above 6500rpm and about 3-6hp below.)
2a Low rpm performance diff? Any
3. Any check engine lights or mechanical/electrical problems?
4. How much?
5. Most important questions. Was it worth it and would you go back to stock?

from what my porsche specialist says, it is useless to chip only, not worth the extra gain and that the better way is to chip and change for sport exhaust, then you'll feel the difference, but the cost is somewhere the 3 to 5 k Euros. is it worth it? if you have the money Yeah!!
