You can't map the standard ECU, you can only do that sort of thing on more modern cars generally You'd need a E-Manage or similar, and you'd get a really small increase if anything, not really any point unless you were using ITB's or something. My advice would be not to spend money on N/A tuning, I'm talking from experience money is so much better off spent on an FTE, you get much more for your cash! Save up and buy a GT/Glanza, you'll soon get bored of N/A power
