no theres nothing, the only thing there is to help, its the safc, it control air/fuel, it could give yu few hp, but doesnt worth the price if yure stock
Even with your 2004 SpecV, it doesnt worth it even if you got I/H/E cuz the trouble of the 2002-03 SpecV that were running lean at low and too rich at high rpm isn't a problem on 2004 and + SpecV. So gatter your money for other bolt-ons
