Well Lefox, i can only say this!
I had the original race kit. As great as it was i noticed some strange behaviour under 3000rpm.
I added open airbox, it was better.
Later on i added Tiforce full exhaust, this was even better with the open airbox and race ecm.
And hey, i ain't refering to the looks, but that is stunning!
I added Remus powerizer and changed to original ecm
this was the best setup so far.
I have never tested Tiforce with original emc only. I know all testing done by Tiforce is with original ecm installed. They informed me themselves over email.
But, i guess you might have a point about the loss down low. Honestly i tend to go faster now, so i really don't notice any significant loss in the bottom end. The bike runs more even, rev way faster and don't suffer hickups and powerloss under 3000rpm as it did with the original race kit. My race kit was installed and tested at a Buell dealer. I never managed to get the bike to run as it should (IMO).
I have to say it evened out best with Remus and original ecm installed. The bike simply behaved way better. I never tried the race ecm with the Remus powerizer. I was informed that testing had proved, original ecm was better (than race ecm), also giving more power. This when using Remus powerizer. Ofcourse, my ecm is for my bike which is manufacturered september -03.
I guess these bikes that were tested, might have been never models. If they are better learners 8the ecms) i do not know. But if folks find it a problem, then it's just add a primary gearing kit. Or?
Maybe, just maybe, it is hard to get it all.
I think it's so difficult to say what's wrong or right cause it's so subjective. I know what i have been through because i have tested it and i know what i notice. This is by far the funniest setup with this bike (as i have tried). I feel like i am a kid driving down the streets. I notice i always smile from ear to ear when driving my bike. It's a feeling i haven't felt since i was a young boy!!!
You all know that feeling, don't ya?

I heard (and hear) dealers say the newer bikes work different than the older bikes to. The newer ecms are worse than the older 03/04 - 05 bikes. On the otherhand it's much talking from some people. I have talked to dealers that seems very unaware of much of the Buell stuff. So, personally i would say it's best to talk to people who really knows and have tried these bikes and gears for real. Tiforce, seems to be pretty unknown and that amazes me since it has been around so long.
