Well, it'* pushing 80* outside, so I figured it'* a good day to check my summer tune. Here'* a scan with my 3.0" pulley.
My timing is low, but I set it there to be safe. I have no KR under WOT even with the higher temps.
So I dropped to a 2.9" pulley.
Compared to a stock pulley.
And here is another scan with the 2.9" pulley.
My boost went up by almost one pound. My timing went up a little as well. AFR is a little lean and still no KR under WOT. I had one small blip of KR at the shift point, nothing to worry about. When I get a chance I'll have to bump up the timing a bit. Right now I'm at 13*-17* and would like to get it at 15*-18* or even a little higher.
