Has any one tried the ultimate 13 for the DFX on the V3i and what were your results?Have been seeing good results on this coil and was thinking it might be worth a try on the V3i even though they are not tuned for it. Then neither were some of the early V3i coils and they worked well in single freq. The SEF coils white and black 112 have been a crap shoot so far. Was thinking the new 13 coil in single frequency might be a killer open field combination. Looking for someone that might have the chance to try it out and report back on it. Thanks Yazoo
