Fender noise problems

I just borrow a Fender stratocaster plus from my friend, it comes with Fender Lace Sensor, the feedback and noise seems quite low, you can try... just search in the yahoo for more detail!

       

Left one is mine, it's MIJ fender ST57-TX (2007), the right one is US fender Strat plus (1991) with Fender Lace sensor pickup
