not having a lot of experience on fuel injection i was wondering if these things actually make any noticable difference when fitted, has anyone got any experience on fitting this item or similar to any other bike??

just get a power commander3 and some dyno time, proper map, away you go

Not a big difference, you might see an extra couple of horse power and it's only in 2nd and 3rd gear from what I can make out. If you were racing on track and you needed eveysmall advantage there was I'd say go for it but for a road going bike I'd rather my money went towards good suspension.
A power commander will give you a lot more, put your money towards a custom map. The SP1 can give some great gains

That's the only mod (although I stuck some cans onPete.L wrote:I'd say go for it but for a road going bike I'd rather my money went towards good suspension.
) I'd consider with the SP.SP1's rock!
Re: sp1 de-restriction box of tricks????
A lot of bikes cant actually make full power in the lower gears (some its just 1st, others its 1st to 4th!)
That box basically de-restricts it so it can make full power...
I wouldnt personally bother with it on a SP :S
Just do the PC3...
Some dirt bikes come with a similar system (The Suzuki DRZ400S/SM comes with a solenoid that past a certain throttle position, it opens and allows atmospheric air pressure to get to the carb slide)
Its either there to meet emissions and/or to stop you looping the bike :S
