i usually don't bother with all those pussy upgrades, like cams and exhausts, air filter and chips, the power u get for spending a sh!tload of money is very little. add 2 more stacks to that and run low boost on a holset turbo, they are quiet cheap nowadays. At least it's an upgrade that i could feel.
