Today I installed the powerchip in my car, and the difference is not huge (this is my first naturally aspirated car in a while, on turbos chipping makes a hell of a difference) but it's definetely noticeable.

I just drove the car a couple of miles today on the way back home, but I could feel the engine responded much better, it didn't ran out of breath above 5,000 RPM like it did before.

I'll post some more impressions after I drive the car more, but my first reaction is very positive.

I can't wait to see if the 155 MPH limiter is gone!!!!
