Recent comment from an ex carb, unblown customer:
Hey Mike, giving you another update. Car is working great!! Car on Saturday went 7.31 three times in a row. only varied 12 thou all day. I had a chance to watch the boost gauge all the way down the track. As soon as it comes off the chip it makes 6 psi and don't move the whole way down the track.
- MANY, MANY reports of .3 tenths drop in ET immediately on installing
