after my delete plates the timing got cut in half. rwdt and eric brooks showed me how to get it back on track. 1-3 she holds steady at 29* advance. but when i go into 4th, i cant get more than 24*. anyone seen this before or know how to correct it? thanks. (05 mustang gt manual)
p.s. i tried raising the .9 load spark and no change. the "combustion pressure limit" table is set to allow a max of 29* but im not sure y it wont allow it in 4th.
