I like The FBO Limiter plate i have three of them in different engines and cars , but sometimes your engine for example only wants 10 degrees of initial Timing, and you want to aim for that 34 total. Well The FBO plate can only give you 18 degrees at minimum so you can only achieve 10 Initial+18 Mech=28 total. You wont be able to achieve this 34 total base line. Wish he sold two versions, another limiter plate for milder motors that has the options of 18 20 22 24. What i had to do is use the fbo plate used a slots that i wouldnt ever need and open it up to get more mechanical.
