Hey Mike, giving you another update. Car is working great!! Car on Saturday went 7.30 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 dont move the whole way down the track.
- Good for .3 .4 tenths drop in Bracket Racing
