Dear Friends,

A few months ago I purchased the VP12 performance chip. It took some time for the chip to work, but after a month or so my sc430 seems to accelerate much more aggresively. However, I wondered if this increased performance was "in my head".

Then the other day I had to take in my sc430 for repairs (thats another story). Fearing that the chip would void my extended warranty, I removed the chip. Almost instantly after removal, my throttle response seem to return to the factory baseline conditions which are much slower.

The point of the story: this VP12 chip really works. The chip improves throttle response and makes the car much more fun to drive, making the sc430 feel more like a sportscar and less like a sedan.

That's just my two cents!! Brett

This is some type of piggyback ecu? Does it let you upload your own MAPS?

I'm no expert, but as far as I understand the chip reprograms the ECU maps and uses the OEM map as the baseline condition. The chip hooks directly to the OBD-II port through several wires. I'm not mechanically inclined at all, but even I was able to do the install. The car just drives much more aggresively; I wasn't convinced until I actually removed the chip and the car went back to baseline conditions.
