I do Not think an ignition is going to enhance anything except provide a higher rev limit... Only... a Spark is a Spark... after all, both will be timed the very same...
so advance curve [may as well get a Sportster module] and rev Limit [again Sportster module, if anything] are the Only real changes....
Pipes... Absolutely... tho I dislike 2-1 personally... they tend to enhance lower RPM performance...Especially if you do Not have a set of Staggered Duals with crossover pipe [O.E.]

The 2ki is better than the 2000p but either is miles better than OEM!!!!!!!!

Have to admit, for Big Boyz's reasonable price I'm tempted to just do it now while the top end is already half disassembled. But, I've already got a new Killer carb and manifold sitting here waiting to be installed, so I'm thinking maybe I just put those on first and see how she rides. Could always do head porting next winter if I feel the need.

I do Not know how you quantify that... But... I cannot tell any difference...and the Modules we have here in the shop are Plug and Play... so quite simple to drop in to Try....

When I switched to the Dynatec 2000p I noticed a dramatic improvement in starting over the Screaming Eagle module that came in my Heritage. I switched back and forth a couple times to be sure.
When I installed a Dynatec 2ki it got even better.
With either the OEM or Screaming Eagle module you have no choice but to let the bike warm up until it's ready to ride but with the Dynatec's I have the ability to hit the start button put the bike into gear and ride off.
Also with the OEM or SE modules if I didn't keep the idle up then the bike would die.
I don't have that problem with the Dynatecs.

Just so you guys know the programmable SE ignition module was made by Dynatek. It's the same as their 2ki.. infact identical curves..
Maybe you had something wrong with your SE module..

I did it by simple experimentation.

Kinda like Folks Claim, some of those "modules" make Kick Starting [Shovelhead mostly] easier... I believe a Dyna-S is slightly [Maybe] better at Kick starts, but, the "module" thing??? I cannot Quantify.... Maybe we needed more of 'em to come thru the Shop??
BTW; I am Prone to Taking my Evo street bike out on the Dragstrip at least once a year... so... Maybe this year I remember to change out Ignition modules to see what differences it makes on the Real World Dyno....

Interesting... we have those modules, plus some other "stuff".. while I never noticed any difference in "Starting" I also have Not paid Much attention to Idle and ability to ride away cold... On an Evo, I have never rode away cold...so...there is some stuff I do Not know about!!!

As for your RWD I highly doubt you will find any difference.
The only difference I've found is with cold starts.
