Power commander for stock bikes

What kind of difference would a power commander make to a stock bike?

The reason I ask is that I installed the software and had a look at the stock map and the PCIII 'stock' map, and there was a a significant difference in fuelling.

I know that you really need a filter and exhaust system to make the most, but considering that the maps were completely different, would it be worth getting the PC before getting any upgrades?

PCs with a stock map reportedly make the fuelling smoother overall. My Blade ran better on a PC stock map.

If you read the bumf they claim that stock bikes are something like 60% optimized due to emissions tests, etc. They then claim 90% or so optimization with the PCIII. It made a nice difference on my stock 05 Blade, especially to the injection response/jerkiness and the R1 had one on when I bought it. I'm not someone who buys a bike and feels the need to mod it but I would always consider a PCIII, especially from the US when we are murdering the dollar on exchange rates.

So the general consensus is to get one anyway - if it's cheap enough. Thinking

I may have to budget for one.

So if the optimisation is better, does this lead to better fuel economy, or worse?

TBH I can't say I noticed any difference with fuel economy, but then it's not something I pay too much attention to. I just sort of put petrol stuff in when I'm told to. Wink

I've just taken another look at the website at the maps, and it seems that either a stock filter or K&N works for any map, it's only the exhaust difference that changes which map to use. Surely a K&N would increase air flow, and therefore need a different map? Or is that why they let you program it yourself if you so wish?
