Tried Tuning The Car But Still a Few Problems

Last night I finally put on all the things in my signature started the car up and it ran... but I took it for a drive to get the engine hot and thermostat open and it had less power then before I did the swap.. 'Micheal Yount' told me to set the timing at around 14* and fuel pressure around 38-40 with vac. off.. I found that with the vacuum off it was running 50psi, so I brought it down to 40 and took it out and it was a little bit better... but not as good as it use to be... it just doesn't have the throttle response. I checked the vacuum and it is good at 19-20 at idle.. so I was just wondering what you guys think... I have drove it for about 5-10 minutes, before I had to go to work so I havent touched it since last night... I am about ready to go out and play with it... do you guys think it just needs to be fine tuned or what??? Maybe the timing has to be adjusted to get the car better throttle response?? don't know please help... The car has a stock cam with 1.7 rockers if that helps at all...

The needle on the vac gauge is steady, and there is no missing or popping, it is really smooth. I don't know what clocking the MAF is though. So should I just mess with the timing?

but the intake matched up nicely against the GT40s, I only got this stuff because everything else was stock. When I bought it, it had GT40s and 1.7 rockers, stock induction and meter and tubing. I thought this would help the car out a lot. What if I turned the pressure down so it isn't pushing a lot of fuel until I step up to a bigger cam?

Maybe I need a longer duration cam to take full advantage of this stuff... Is that my problem?? My valves are opening more with the 1.7's but they aren't open for very long? Could that be the problem... and would it hurt to drive my car like this, cuz it is my daily driver and it would take some time to get a cam and the time to do it.
