Just found this thread while researching ecu tunes.
Wow...amazing stuff! I was really interested in and researching the FT86sf Stage 2 tune package...until this, wow....200whp?! (dynojet is fine) ...I think the decision to go with your tune is pretty easy (not to mention, SD is actually close/reachable to me). ..you guys must be some really talented tuners
btw: about your 91oct 200whp tune... which additional parts do you speak of, that are "needed"/required to hit your goal/mark? ...a full header back exhaust, or full cat back exh, I assume?
I don't plan/want to change out and upgrade the op/fp/exhaust and want to leave those parts stock (for DD incog'ness, I like it oem quiet and also less cops) ....BUT, I am down to change the headers to the FT86SF catted headers, just for performance (and of course, a drop in filter)....would the FT86SF header alone (with all the rest of the exhaust bits stock) be enough extra flow to reach that 91oct 200whp mark/goal with your new 91oct 200whp tune??
