Where the chip is in that picture (example only) there will be a large metal clip, secured from underneath the board which when removed, will reveal the chip as above.

Be very careful when handling the ECU board, they are sensitive to static.

Also, I'm pretty certain TT didn't do a chip for an RST (at least not their own) they used other methods to 'chip' RST's. Nearly all tuners will put a sticker on the chip - usually one that identifies the tuning co & possibly basic spec'.
