Tmax/TTS
Can anyone convince me why I shouldn't (or should) dump my TMAX and switch to TTS or a PC? As I've sunk a few bucks into this motor I want to wring every last bit of power out of it and it doesn't seem to me I'm getting it especially after looking at some of the 95"-98" dyno charts. The bike runs well enough but I expected more as compared to my previous build (98"/37g/street port heads/9.7 comp).
None of the maps available seem to be real close to what I have built. How do I know how close the timing is without a dyno or what AFR's to even shoot for?
The closest map as recommended by Zippers is a 95" with a 50mm Zippers throttle body and a Red Shift 577 cam and Thunderheader 2-1 where mine is a 98" with a 48mm HPI. and a WT 26 cam and a Fatcat. Is that close enough? How am I supposed to know? At this point it feels like throwing darts blindfolded.
If I have to dyno this to get it right what's the advantage to the TMAX? Am I missing something or is this better suited for someone not trying to get every last bit out of their build? It seems I might be better off with a TTS and a dyno tune. Any comments will be appreciated.
Thanks,
Rick

Do you have the T-Max w/Auto Tune? If so, you shouldn't need a dyno, because the T-Max most effectively tunes itself to your riding style and engine build. You start with the closest map and the Auto Tune feature does the rest. How long have you had the T-Max on your bike? You should really give it several months before making the decision to dump it.
You really want some power? Spend a few hundred more and get the NADS dry nitrous assist system from Zippers, which piggybacks directly onto your T-Max. It'll knock your socks (er...boots) off!

the autotune will tune the afr, but not the timing. Thats the reason for the dyno tune. You'll just have to lock the autotune down once you have the bike tuned.

Its possible I may not have understood some of the previous posts I read, it may be regarding the SERT upgrade path. Mine is an '08 so I don't really read those ones to indepth.
