From all the reading I have done over PCIII's, they are not really worth the money. A full intake/exhaust system along with a ZX-6R rear spring are the best things you can do for an SV

Based on my own experience, I'd say the PC3 is worth the money. I picked up my PC3 for $175 on this site. I installed a full yosh system along with the PC3, which has the Dynotech yosh tune. The difference from stock to full yosh with PC3 is very noticeable. My SV pulls a lot harder now, compared to stock, from low revs all the way to redline in all the gears. After the suspension, it's my opinion a full system with PC3 is the next best mod for the SV.

A PCIII is very worth it. All modern bikes run lean for emissions. Richen them up and your bike will run better. Add a pipe, a K&N and a PCIII and you WILL notice a power difference because your bike will run better.

Does anyone have Dyno sheets on the actual power difference? I'm interested in how much of it is simply a better torque/power curve and how much of it is actual peak power gains?

They are worth it only if you spend the money getting it dynotuned. Downloading a map from the internet is a waste of money. Expect to pay 150+ for the custom map.

Totally agree with getting it dynotuned, but the maps on Dynotech's website can be downloaded for free. That got me up and running, but my yosh can is cut down to 12 inches, and will soon be 9 inches, so I'm loosing back pressure, causing the engine to run more lean than the map intends, leaving hp on the table. Once I get my set up to the way I want it, I'll start saving for a custom tune, which should be easier for the tech since I already have the PC3 with USB installed.

Regarding the torque/hp curves, you should be able to go to the exhaust manufacturer's website and look at torque/hp curve differences from stock to slip on to full system. I do know that the yosh system gives a better torque and hp curve over stock from about 3000 to redline, while the M4 system isn't as good as the yosh in the midrange, but gives a better top end hp result. IIRC, the yosh system nets 74hp, and the M4 nets 76hp.

Also, can't forget to mention I took 10 pounds off my SV by installing the Yosh system.

Think 300+ for a custom map on a Powercommander from a top tier dynotuner and it'll take a couple hours as well. There's a LOT of work that goes into a properly customized fuel map on an SV. Even reflashing the ECU takes about an hour, and that's a muuuuuch simpler fuel table than the PCIII.

I have a dyno tune scheduled for thursday, and will know the answer with dyno readings to back it up then.
I have an FMF full exhaust, stock airfilter.

I am going to Dyno Solutions in Brookfield, CT and he charges $250 for a full custom map, in 250 rpm increments, with individual cylinder mapping. Net reviews are all good, and he only does dyno tunes as his entire business, so I am hopeful he'll do a good job.
