Serious problems with PFG-01

I have serious problems with PFG-01. The images I have done with Agfa 8E75 before were quite bright. Though I´m using a new-but-used and stronger laser(ca. 6mW HeNe) and longer exposure times, images have never been as bright as they had been with agfa. I was used to light 30 secs with a 2mW HeNe. Now I have to expose more than 2 Minutes. Thus could anyone please enumerate his/her knowledge about PFG-01 concerning exposure(times etc.) and, possibly, developing to support me ? Bye Thilo
