Re: My Winter Upgrades

Did some more pulls, and slowly upped the boost. I'm at around 30psi now. Car is definately feeling a lot stronger. The AFR curve isn't perfect, but not too bad. Stays in the mid/high 11's the entire time, and I'm happy with that. Did have a misfiring issue, but just cleaned up the plugs and gapped them down to .020, and the problem is gone.

Here's another snap shot of the log from my last pull of the night. There are a couple spots where there was a very small hint of knock. I'm still running BPR6ES plugs, and just picked up some 7's. I'm hoping the colder spark helps alleviate that knock. I stopped adding timing at 21 degrees. After the new plugs, it may take more, but I don't think I want to add any more timing, don't want too much cylinder pressure. So the plan is to just keep adding boost, probably up to around 35psi and stop there.
