Hey, been like forever since I posted. Anyways, finally took a couple of suggestions I got here long ago for my carb turbo. I took my carb into the shop for a rebuild and had them up the primary jet one size and the secondary two sizes. I can now run my boost at 14psi with no evidence of detonation. I plan to take my psi up by 1 every week to see how high I can get. I'm shooting for 15 psi. Let you know how it works out.
