We'll answer alot of questions with finality now. This year we'll have a wide variety of different SC setups to compare. We'll have to be johnny on the spot with temp measurements both days right after each run.

Started to tune. Ran through the 3.4 and 3.2 pullies with 0 KR no problem on 91 octane pump gas. I dropped it to the 3.0 and am getting blips up to 1.5 randomly throughout the MAF range. So I added a little more fuel and it cleared most of it up. So I am pretty sure on race fuel it will be great. Registered 12.5# boost, but couldn't finish off the run due to a misfire problem. Only ones I could get to register on the scanner where number 1 and 2 for some reason. Number one was misfiring pretty good, but two was okay. Don't know about the rest of them. The weird thing was that when I am driving around at normal throttle or even into boost easy it runs very strong with no misfire at all. But as soon as I put my foot into it is started missing. So I pulled all of the plugs and checked them out. All looked great and even burn on all 6 cyl. I had the gap at 54 so I narrowed them down to 48 as recommened by a trusted source and it was much better. But I could still feel it misfire every now and then with a full WOT run. I am running stock wires with MSD coil packs. I have them re-routed under the snout and they go right by the alternator and even touch it. Could that cause an issue? Wren suggested spraying mist around them but I couldn't see any problem. Checked the OHMS of each secondary terminal. All at 7.8 as per the techinfo. I didn't take them off to do the primaries.

Here is my new badge too by the way. I like it.
