ECU Chip Upgrade
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.
