I wanted to post my combo again with the some changes I made to the program. As of right now everything is running much better than when I was trying to get info out of MSD a few weeks ago (still no response from them), oh well. The drivability issues have really improved and even though I have more tuning to do to get the system fine tuned I can at least enjoy my car now.





Here is my current set up.
