Most calipers do not want more than 1200 psi. You can get some caliper pressure gauges from Longacre for about $100 for 2 gauges and a cool metal case. For C5 sized brakes front and rear I was getting 1100 psi front and 850-900 rear with about 100 lbs leg pressure. I ended up with a 3/4 front and 3/4 rear on mine, but the rear sizing was due to 335/19 tire that was 27 inches tall. It could take more rear brake and still be ballanced.
I am going to guess that your problem lies in what brake pad you have up front. If you are running a street pad, I would change to something more agressive. I tried the Wilwood BP10's and could not get my car to stop no matter what I tried. Went to a Carbotech Ax6 (autocross pad with good cold bite) and it was a night and day difference. They will be dusty and will make some noise. Mine never made any noise, but I have heard other people say they do.
I have not tried but heard good things about the Hawk HP+ as well.

I was also going to say pads, but our red 69 has 14" proplus front and rear with a 1" wildwood master and it is awesome with the pads supplied by Baer. my nova has 3/4 f and 7/8 rear with 14" proplus and it to is good but I do run a wildwood auto x pad
