Basically, all a stage 1 download does is change the range for the ECM to compensate for the added air flow the "stage 1" air cleaner they put on, by adding a bit more fuel into the mix. More air=needs more fuel.
The more air vs fuel your bike has, the faster it'll be but the harder it is on engine life. This is running lean.
The more rich your fuel is the cooler your engine will run and it'll run a bit smoother. It'll also help w/ engine life.
The goal is to get a good balance between the two.
I know you like those Radius pipes (and I used to have them) but the fact is: they suck on low end torque. they're great at higher RPMs but off they line they are awful, and I wouldn't be surprised if they accounted for 80% of that sluggishness you feel. If you had the stock exhaust on then put those on, it's a noticeable difference.
Right now w/ the canned stage 1 map, your bike is just running lean and not rich, which really means it should be running pretty good off the line. Not like a dyno'd bike mind you, but basically how it was before you did the stage 1.

Exactly, you have done all the easy stuff and it just needs to be tuned. If its still not fast enough you will need to get into cams and more displacement.
