Progress: Rockers OK / TP voltage is also OK

OK, so I made what I guess could be called a little progress today. I got the rockers adjusted and tightened down, and got the poly locks in really good this time.
I also verified the TP voltage. Its .985 at idle (the car idles great) and 4.64 at WOT. These values are OK, aren't they.
Anyway, I took the car out for a spin after this and its a little better than before, but it still doesn't really accelerate. Its still a ton slower than stock, but at least it will accelerate. It was raining and I can't even break the tires loose on the wets roads, but like I said its better than before.
I guess my next and just about last option is to buy a tweecer. I should have the money in a week, so hopefully that cures my problems. If anyone has any other suggestions, I'd love to hear them.

BTW - fuel pressure is at 42 PSI with no vacuum and timing is at 13*.

The motor runs idles fine and runs very smoothly when I am accelerating. I have double and triple checked the hoses and wires.

Paul - I didn't delete a ground strap, that must be someone else.

Does someone want to give me a list of where all the grounds should be hooked up and some that are easy to overlook.

I agree that this doesn't seen like something a tweecer would cure, but then again, I don't know much about the computer and how it reacts to stuff.

I know I'm not going to solve this one overnight, its just getting a little frustrating. Thanks for the input guys.
