Hi All,

Today installed a ZZP 3 inch downpipe, an open cone filter attached to the end of the stock intake tubing (where it meets the stock box), Poly mounts, shorter dog bones, and ive already been running autolite 104s. I have a 180* tstat but haven't installed it yet.

I just did some pulls with the stock pulley and I am seeing an average of 3.5* of KR Via Torque with a peak of 5 at the top of 3rd (not shifting). Any ideas what could be causing it? I pretty much expected to be Knock free with these mods on a stock pulley.

is there anything i can monitor via torque to troubleshoot?

My first thought is a clogged fuel filter.
