Great job ACG and Weistec.A little patience and you shall be rewarded.
Impressive numbers. Will this car ever see track time?
This is certainly making my decision much easier. Have to start
saving my pennies.
Isn't that A/F ratio on the rich side? Couldn't you have leaned it
out just a bit and made some more power?
Based on the graph it looks like it started very lean and
finished off at 11:1.
How did you log the A/F ratio? tailpipe sniffer? If so, this would
explain the lean condition at low rpm's.

Now just imagine a C63 BS with this Stage 2 and the track package.
Must....resist....temptation.....

A/F readings were from the Tailpipe... could have leaned it out a little more but honestly with the gas we have here in California.. its better to be on the safer side then on the upper limits.
