Looking for advice on a starting point on tuning.

FBO sells 14* MSD bushings. Problem I have is my engine kicks back with anything over 18 initial.
FBO? I'm ordering the 10* bushing off ebay and I'd like to order 14* also. Is there a link for FBO? How about someone who offers a kit with bushings ranging from 10* to 16*. I should have posted this whole thing BEFORE I spent my money on a non-programmable box. I'm getting tempted to buy a programmable box at this point.
