car on road, but need help

So this weekend i finally got my 68 camaro, ls1, t56, frost tuned on the road. oil pressure is great, coolant flow and temp is great, only code is the 1-4 shift sensor, but heres the issues

1) My autometer electric speedo doesnt go over 20mph, my autometer tach doesnt go over 2k.

2) the car idles perfect but every once in a while it will die. i have to hit gas to keep it a live.

3) when I get the speed up a little the car seems to boggs. like it doesnt want to go..

anyone know what or where i should look to get these thing fix?

one more question, would the cpu need to be programmed for my truck maf?

The pcm is probably still putting out a 4 cylinder tach signal. Change the tach wiring to match it. For the speedo, did you program it per Autometer instructions?
