Finally had time to get this gas tank cleaned out and reassembled with a new pump sock and filter. The 5 micron post filter was severely plugged which was likely most of the issue. Low vacuum and associated late/hard shifting was caused by retarded ignition timing. All straightened out and he's running like never before. Finally had time for a wash yesterday and also did clay bar, polished the hood and waxed. Here's my little test spot on the hood.
Full on pics when the weather clears up.
Any doubts I had about the FiTech have gone by the wayside after correcting the timing issue, looking forward to more smiles and miles, driveability is Soooo good
Pretty good, a few gripes. The accel pump function and starting fuel do not self tune so still getting it dialed in. Also thought the motor was running too cool but it turns out the coolant temp sensor they come with is garbage
