Any lag with Matrix Infinity @ PAL-TV?

I’m in the process of getting a new PS2 with a Matrix Infinity chip in it. Going to import Accent Core and 3rd Strike from the US (living in Europe). The thing is, I have a silly old CRT TV that just takes PAL/SECAM, but I’ve read that whatever game you’re playing, with a mod chip, you can still output PAL with an imported NTSC game. So, my question is: have anyone tried this, and does this add any lag?

While the chip can force color to PAL I don’t think it can do anything about the refresh rate, thus the game would play at the correct speed but your TV has to be 60 Hz compatible.
