So I've done a fair amount of research regarding tuning the DE motor after intake/exhaust mods. I've run the past 50,000 miles with the following mods:

motordyne plenum spacer
K&N drop in filter
Megan racing resonated test pipes (thinking about buying the ART pipes now)
Fast Intentions true dual exhaust setup (one of the earlier designs)

I'm about to do a clutch job which has rekindled my interest in mods. From what I've been seeing with dyno graphs of other members rides, my A/F numbers have probably been crap the past 50,000 miles! I'm about to hit 110,000 miles and haven't had a single problem out of this engine. Is it worth it to go ahead and get the Osiris UpRev software on this engine?

Just looking for input guys, Thanks.

 

No reason not to do it provided you have someone who can do it properly for you... get things tied up nicely!

Only thing is when you feel the difference you're going to regret not having done it 50000 miles ago!

I don't know if going from resonated TPs to ART pipes is worth waiting to tune for- someone else might need to weigh in on that. The difference there may be minimal but if you're going to do it... might as well get the most out of it that you can.

 

You need to get tuned ASAP. And replace your spark plugs. Seriously, you will be kicking yourself in the bum for not doing it sooner, lol
