After making the switch to a 1g head, TB, IM, 1600s and E85 I'm getting erratic part throttle cruising. I thought it may have been the fuel trims but after dialing those in the problem still continues. I was also researching about the idle switch on 1g TBs but I swapped my TPS from my 2g TB over so that can't be the problem. All the bases have been checked. Boost leak test holds 23 psi and takes 90 seconds to leak down to 0. Base timing, plugs and wires are all brand new. Below is a log of the throttlepos values with the car off and a part throttle cruise log. The problem is very noticable at 108 seconds
