Brand new tensioner didn't make a diff. It is what it is I guess, I just cranked the timing back up to 19* with the 3.1. Ran a 12.84 @ 108 today so it must be doing something right
wicked! which cam is that you have? you have a gen V or III?
also that cam could make a big difference in boost. like my NIC has a lot of overlap and leaks boost, do you have ported heads? that will lower boost as well
