Decisions, decisions! Shift kit or tune...
Here is my quandry:
Would I be better off to
a_ have a shift improvement kit and trans cooler added to my 5R55s (and in the process change the fluid/filter which is at 45K), firming up the shifts and giving me better performance and reliability, or
b_ purchase a BAMA tune, firming up the shifts and giving me better performance/reliability and just change the trans fluid/filter
From what I have read, the tune is most effective in a V6 with an auto trans, due to its adjustments there, and not much gain elsewhere without other mods. I've also read that the shift improver makes a marked difference in the 'butt dyno' (which as a DD is all that matters to me)
Both will likely set me back about the same amount. Oh, and what happens if I end up doing both? Will Bama take into account the shift kit when I order it and adjust my tune to correspond? Will I still see any additional improvements?
