there is no inexpensive way but you dont need a chip yet. Trust me your far from chip stage it might help but get every bolt on first then look for an SCT SF XCAL2. The chip wouldnt do much for stock cars or almost stock.
I disagree with that. A tuner, not a chip, is a good thing at any stage. A tuner will make a difference even on a stock car and can be used to modify later with any bolt-ons. If he bought a tuner, most supply at least one power tune and one mileage tune, these are both good ideas on stock or modifyed cars.
