Any one had experance tuning a stock compression 6L with a LSA blower, it's running 13 psi and seems to get a lot of knock down low around 1500-3000. It will make about 13psi at 1500rpm that's a lot of boost at low rpm!, I can make it knock less with f all timing but it runs like a bag of shit. On the dyno it would make more power as I would add timing but I could hear knock at any thing above 12 deg but it would still make more power with more timing and not just up top it would be over the hole rev range. So any thoughts on this boost level at this comp?
