Well I was aware that the tuneboy unit alters the ecu/pcm map's for 
fueling and ignition. I have used various similar devices on other 
bikes and cars. What is did not remember or know were the following things;
1. Is the tuneboy a reflash device or an interceptor?  Someone else 
gave me that answer already its a reflash ubit. I did not pick up on 
the locking the device to the bike, that should have been the give away.
2. Does it really make a noticeable improvement in the performance of 
the stock bike? Not by much apparently, but I still do wonder if it 
would really improve the stock bike. I know that it can go either way 
when comparing to the stock mapping.
3. Is it needed if I'm buying a bike with an aftermarket exhaust and 
BMC air Filter? This is still not convincingly answered.

That I am, but I have not had a chance to learn much about the 
triumph ecu yet.
Ever since I 'found' 32hp in a ford four cylinder by some simple 
little mods (free flowing unkinked/uncrushed exhaust, replaced the 
entire air intake before the Throttle body, retarded the factory cam 
4 degrees, matched the fuel injectors, replaced the timing pickup 
with a billet piece, added a properly shaped oil pan) and gave it a 
complete dyno tuned chip. I have been aware that most EFI setups are 
compromised because of government noise, emmissions and warrantee 
laws. Now things have come a long way since 1988, but I'm certain 
that power can be found in custom tuning.

Well, my goals were simple to get the best set of maps for the sprint 
with whatever exhaust I decide upon, a BMC air filter and two 
different grades of fuel (Regular and premium, if that makes a 
noticeable difference). Once I get the Sprint to that state of tune, 
I would put the tuner away and probably not touch it again (unless I 
change hard parts).

Sorry, I'm not a poser, and really can't stand those who are.

Gee, I'm a little surprised at that. I mean most of the automotive 
tuners that 'lock' themselves to a particular vehicle can be 
'unlocked' after returning the vehicle ecu to the stock maps.
You, can't do that with the tuneboy?
That's a shame.
On the other hand, what I was asking was Unlike the PC III on certain 
new bikes, was having the tuneboy with a copy of the laptop software 
a plus in the deal or a minus. I mean a buddy of mine bought his 04 
VFR new and the dealer sold him the PC III tuned for his bike and it 
caused lots of problems with the ECU. I don't want the tuneboy, if 
that is the case with the sprint st.

Thank you for the info Chris.
