[QUOTE="LavaSlide, post: 16523218, member: 123838"] When I say dropping cylinders. As I have not encountered a spark blowout from boost before but sounds logical. It seems to start missing under boost 12lbs and above. I had posted a dyno run with the car but had the fuel from when I bought it to see if it was a safe tune. It started to go lean at 5100. I know now it was running E85. This was 1/2 tank and I had just filled up with 93. I have done the compression test when I put new plugs in. The gauge that I used seemed to read low but I did get a consistent reading on all cylinders. Not sure what it is supposed to be for being a dry cylinder. I was getting readings 118 to 125.
