ECU Chip Upgrade

[CV580]

The car: 2001 Boxster 2.7

I am considering upgrading the ECU chip. I have spoken to three sources 1) GIAC 2) Upsolute 3) Powerchip. I am looking for customer results, support, satisfaction, and most important - true resulting performance after the upgrade

They cost is more or less the same - within $100.

Upsolute ads and website claim the best gain of all. They have an installation facility within 150 miles from home. The others require pulling the ECU and sending it overnight (downtime - 3 days).

Is there anyone out there who had experience with these upgrades and is willing to share that experience?

Any comment or advise is welcome.

imo, there all bs

The chip would be pretty far down my list of modifications after the last three years of "building" my car. I had the GIAC software loaded in my car a couple of month ago and have not been overly impressed. In both spirited street driving and a day at the track I really didn't notice much difference. While I have experienced huge improvements in other vehicles with chipping the Porsche engineers just didn't leave that much on the table.

From personal experience, I would urge you to go with GIAC out of those three.

As with all normally-aspirated engines, gains from chipping will never come close to the benefit a turbocharged car will see - it will be a modest gain, especially on an engine where the manufacturer has gone further down the road towards maximizing stock power than most mass-market manufacturers will. Lots of people seem to forget that, or haven't had previous chipped experience with either a turbo or normally-aspirated engine, which is why they are disappointed.

Whether such modest improvements are worth the price is up to you. The fact is that there is not alot of additional power to be squeezed out of these engines unless you are going to add a turbo- or supercharger.
