I have not tried the PC, but the Race Tuner can only be tuned buy certified HD mechanic whereas the PC can be tuned by most any mechanic. I have trouble finding a mechanic that can tune my RK to my satisfaction. Next time I will go with the PC!

As far as I know it's the same trans used in the 110 ci. which has more HP & torque in it's stock form.

I am not defending them. Just telling you the reasoning they are useing. But as for the 110 screaming eagle. My 103 stage 2 with the pcv is tuned and dyno to have more h/p and torque than the factory 110. I am sure my local dealer will honor my warranty. It all has to do with the people you are working with.

I may be off base on this... If I am wrong I am sure I will be corrected but from all I have read this is the short of it........
SERT, SEST Mastertune allow for full tweaking of the stock ECM. They can adjust timing if you are ever doing cams. They can tweak almost every thing in the ECM..... idle, Throttle body pressure responce, knock sensor, temp adjustments......etc They require a dyno or user interaction via the software to optimize the tune.
SEST is the more recent version of the SERT.
PC, PCV, fuel pack....etc run after the stock ECM and only control Fuel/Air ratios. They dumb down the factory ECM... They are effecive if your mods are typical stage one. Maps for most stage one's are available for download at no cost. They get you 80-90% optimal.....
The choice is really based on how much you want to spend and how much you want to leave on the table performance wise.......

This should be some interesting reading for you concerning tuning programs:

The dealer/MOCO has to prove a direct correlation between 5th gear failure and PCV as the cause. That said, it would be a hassle but then I'd file a claim in small claims court for down time/etc. When I do a cam swap, I'll be changing my EFI management. The PCV thru Jamie, with a close base map is $305. Their are new/unsealed SEST's on EBay now for $225.50/shipped and these ARE the current #'s listed in H-D's catalog. For me, my 1st upgrade will probably be a cam and .030 gasket upgrade. "Maybe" eventually upping to a 103"cid configuration but that's it. Bottom line for me is complexity and the PCV sounds much more user friendly for the average person and a simple build. And for the "average" street rider, it would be more than adequate I believe....
