HAHAHAHA...Yeah, my tires are pretty flattened out at this point too after sitting for a year...lol...good news is I have a single wiring issue with a fan relay to tackle and this is DONE. I put the truck back up on the rollers yesterday, and did some final street tuning...had to lean out the idle a bit but other than that...speedo and ECU were good for speed signal and looks like the registered speed at the gauge was as good as it always was...probably a tire thing because it always registered a little faster than actual.
