Adafruit 2.8 tft lcd touchscreen

How do I change the spi pins of this Shield from 13 12 11 ??

Library:

https://github.com/adafruit/Adafruit_ILI9341/archive/master.zip

From the header file:

  Adafruit_ILI9341(int8_t _CS, int8_t _DC, int8_t _MOSI, int8_t _SCLK,
		   int8_t _RST, int8_t _MISO);
  Adafruit_ILI9341(int8_t _CS, int8_t _DC, int8_t _RST = -1);

So you would use the first form of constructor if you want to bit-bash.
You use the second form when you use the hardware SPI.

Why, do you want your updates to be slower? The SPI hardware is the fastest way to send serial data out to devices, at clock speeds up to 8 MHz. Anything else will be slower.
