TrufSwapping your ecu isn't going to help, nor will any "reprogrammers" or "performance chips". All they do is change your air/fuel maps and kill your motor quicker with very little gain if any. If you're trying to see significant gain with a d series motor, you'll need to go forced induction, or crack the piggy and build the engine to it's limits. There are no secret weapons or shortcuts about it... to make an economy car that can barely do 100whp go fast... it takes money. If you're serious, I'd start working out a budget.
If you really want to make your car quick don't bother with the bolt ons. Just start saving now and hold off for a turbo. Screw that instant gratification stuff and you'll be happier when you get that turbo.
