Hey, i have a 98 FI GSXR 750. One of my first mods was a TRE, but then after i got an exhaust and a power commander i took out the TRE. I assumed that the PC2 map would alter my timing so i figured i didn't need the TRE. However after playing with some different maps i found that none of them adjusted the timing at all. Now my question is do i leave out the TRE and customize the igniton maps myself (if so how much advance should i use and for what RPM range), or do i leave the igntion maps at zero and re-install the TRE. Thanks, any opinions and ideas are appreciated.
