That's about the extent of it. I spent (wasted?) a lot of time tweaking and modifying the Dodge truck TBI system and really didn't get much of anywhere. I was able to knock the worst of the rough edges off its driveability, but that's it. It really is a cheap and nasty, poorly-done system. I had another round of mods in mind that might have improved things a little more, but it would have been a fairly complicated (time-consuming, expensive) effort and I wound up selling the truck. I'm sure it still starts reliably!
TBI isn't as nice as port fuel injection, but a well-done TBI system is way better than a carburetor and it's a lot less work and expense to retrofit TBI than to retrofit port fuel injection, no matter whether you're using all new parts or all junkyard parts.
