I was starting to lose a bit of coolant over the past few weeks, so I decided to swap LIM gaskets and add a new UIM & gaskets, cleaned the TB and installed a new MAP sensor. I did nothing crazy on the LIM, I had a spare, so I worked on that, just in case. I just cleaned up the ports jagged edges and got as much crud buildup off it as I could. I modified the UIM runner'*, like TheDude did his: http://www.bonnevilleclub.com/forum/...ic.php?t=93856
. Lower RPMs it does much better, revs to 5750ish now instead of 5500, the pull at higher RPMs is much better, Revs faster, best mod I've done so far. From a dead stop and the TC off I can squeal the 235 wide Pirelli'* without a hitch. Used FelPro LIM gaskets and Dorman UIM, Runners & Gaskets.
